[meteorite-list] AD: Special: Extremely unusual Eucrite - NWA 5473
Dear Friends of truly unusual meteorites, in a Quick-Special, we want to present to you a very uncommon and weird new eucrite. Just take a look and you'll agree, that we have here a HED of quite unique appearance: http://www.chladnis-heirs.com/special-nwa5473.html It is a polymict eucrite, but extremely shocked. Instead of displaying as to expect textureless impact melts, the matrix consist of a large variety of grains and finest fragments, looking almost like have been sprayed around. Very hard to cut material it is. Here and there large lighter clasts are preserved. A strange play of colours it has. We had held back that stone for two years, usually if of new material somewhat more gets available, it will appear very soon with different numbers. Not so with that one, we are not aware of pairings since. NWA 5473 Sahara, 2008 tkw 45.9g polymict EUC Shock level: high Weathering grade: moderate Only a small stone it was; with such fast-going exciting material of very limited availability, we have always to vary a little bit, because of the different time zones, where to publish our Specials firstly, to be more fair. This time we offered NWA 5473 three hours earlier in the Germs forum, and all slices went immediately. But, the good news - the main mass of 23.2g is still free. And the better news - we priced it fairly cheap for such a quite unique material: 20$/g. The polished cut face of the main mass is a little bit reflecting in the photo, it is looking as fine as the slices do. So here you are! Good luck!

[meteorite-list] AD: Special: Especially r are EL4 - at an especially affordable rate - NWA 6 482
Dear meteorite friends, Our newest Special shall be about an enstatite chondrite! The enstatite chondrites, the most reduced chondrites, which have formed in the inner solar system and plot on the terrestrial fractionation line, are a rare group and became only recently more widespread by the mega-find of El Haggouina and pairings. Unfortunately El Hagg is so strongly terrestrialized and altered, that hardly and only in a very few pieces still chondrules were visible, so that initially it was classified even as an aubrite. Now we present with NWA 6482 more representative specimens of that intriguing class, showing a lot of nice and distinct chondrules and it was still fresh enough to emit a strange smell while cutting most probably from the exotic sulfide minerals, which are so typical for the E-chondrites. The material is somewhat crumbly, so that we let the slices unpolished. And with NWA 6482, were able to offer an extremely rare petrologic subtype: It is classified as an EL4. The Bulletin database coughs out only 6 non-Antarctic EL4s (DaG 734, DaG 1031, HaH 317, NWA 4780, NWA 5409, SaU 188). with a somewhat modest combined tkw of 2.8 kg. ..and additionally 5 Antarctic finds, totalling to a 0.2kg. So we think, that our offer should be an excellent opportunity for the systematical collector (and of course for all others too!). We have to confess, that we had difficulties to set a price for this new meteorite. Enstatite chondrites, besides the fossil El Hagg, are traditionally a somewhat costly affair, well and now we have here an almost unobtainable subtype. A web-research, if you like to do, results for EL4s always in a few offers of the remainders of the Dar al Ganis, at prices around 150$/g. You know, what we did? We sat down, looked out in the fairy-tale-snowscape and said Christmas is coming soon 10$ a gram, as long as stock lasts http://www.chladnis-heirs.com/special-nwa6482.html And hope to make you happy with that! All the Best!

Re: [meteorite-list] AD: Special: NWA 6349 prov. - a PRIME Brachinite at a low preferential price
Dear meteorite friends, As a starter for our new meteoritical year, we chose for our Special a truly especially convincing offer: An excellent brachinite. The class of the brachinites comprises quite heterogeneous members and their genesis and the kind and history of their possible parent body isn't fully understood yet, which makes that type so thrilling for the actual research. To avoid iteration of former discussions and explanations on the brachinite-group here on the list and in our specials and in fully recognizing, that no one could better present the different types in such an up-to-date and comprehensive manner than him, we recommend to consult David Weir's famous meteorite studies homepage to get an insight into the brachinite-topic. With NWA 6349 today an attractive and very elegant representative of its class climbs in the ring. As you see already on the pictures, NWA 6349 lacks the brownish tint and color, which other brachinites commonly share and which you connect with that type, remembering the illustrations in the books of the classic one, Eagles Nest. It is, because NWA 6349 isn't so weathered like the others, but of a still good freshness. With several new numbers in the recent 2-3 years - and also the Bulletin database not yet fully updated with the newer ones, (but also the holders of samples of them being somewhat scrooge in loading up photos of their specimens in the EoM), the situation with the brachinites is currently still somewhat opaque. We personally believe to see actually 4 complexes: - NWA 3151, highlighted as the first true BRA from NWA + pairings. - NWA 5471 possible pairings - The stones around NWA 4882 NWA 5969, the latter the freshest of all - And let us add, although no brachinites, the recent brachinite-like numbers NWA 5400 et seqq. There are indications, that our NWA 6349 with its 730g tkw may be a pairing of NWA 4882. Here are coming now the slices, as always with one polished side: http://www.chladnis-heirs.com/special-nwa6349.html Despite the recent numbers and nevertheless, a glimpse in the Bulletin Database shows, how shockingly rare that type is (and of what for a crucial importance the NWA finds are for research); The quality of the NWA 6349 material is evident, the price of the alleged possible pairings maybe here and there in the back of your mind, so that we finally think, that our pricing of 40$ a gram will make NWA 6349 for the collector curator to an especially joyful brachinite.

[meteorite-list] AD: Special: NWA 6021 - a very pretty CO3
Dear fellow enthusiasts, Here in our actual Special, we want to introduce a carbonaceous beauty, a new CO3: NWA 6021. CO3s were and are still a little bit underestimated in the favorableness of the collectors. They never got the popularity of the CVs and CMs, most probably, because they hadnt these massive falls like Allende and Murchison of the direct Apollo-period, which consequently were not only easily available, but discussed at length and pictured in each and every popular book. While the most important CO3-fall, Kainsaz, was locked away for the collector behind the iron curtain, else there were only Lancé, Ornans, Isna and Colony all with very modest tkws, museum stuff, with limited opportunities to gather a small cut and so costly, that the whole class was something only for the very experienced and specialized connoisseur. Really available the CO3s became not before the 2nd half of the 1990ies, when the finds of the larger pairing group of the DaGs in Libya were made. Additionally another reason might have been, that CO3s are of not so striking first appeal, but CO3s require a closer look. Though that attitude has already changed a bit with the fall of Moss. And do you know what? The novercal neglecting of the CO3s by the collectors is absolutely undeserved. One has to examine these rocks only a little bit en detail, if you allow them to come only a little bit closer to your eyes, an incredible cosmos will open to you, richer than in any other of the carbonaceous types! CO-chondrites have chondrules to excess, sharply defined and not very metamorphosed. Their matrix is similar to that of the CV3s, as well as the chondrules composition, theyre only much more smaller, so small like those in the CM2s, but they have three times more chondrules than the CMs and they have many more olivine aggregates than the CV3s. And yes, they contain CAIs too, the reason, why you bought once your first Allende. One has it all and more than that but on a miniature stage. Take a magnifying glass and youll recover what for a wonderful and fascinating affair the COs really are. Now with NWA 6021 were glad to introduce an aesthetically especially pleasing representative of that class: http://www.chladnis-heirs.com/special-nwa6021.html Densest clouds of chondrules! To some of you immediately will come the gimmicky title into mind once attributed to the later Kainsaz-finds: the Space-van-Goghs. But other than with these, the stainings causing these wonderful patterns are in NWA 6021 not so brown oxidized. For you being able to enjoy the full beauty of this meteorite also on a minor scale, the slices are of course professionally polished. The price for these daedal pieces of art by nature, is somewhat under average, the slices are of good sizes and though for every purse affordable. And we are convinced, that your specimen will bring you satisfaction and hours of joy on long winters evenings.

[meteorite-list] AD: Special: Truly Perplexing New Rumurutiite NWA 6022 prov. ( budget slices of fresh BRA NWA 6349)
Dear meteorite community, today we demonstrate once again, why our Specials are called special. We have here a new R-chondrite - which alone, also in our spoiled times, is something very remarkable. - But.. Usually, as you know us, we would explain the particular properties of the type, chemically and textural details, perhaps we would make some historical excursions, would tell about statistics, masses, ev. a little price availability discourse ...and so on. But here? I think we should simply let you alone for some minutes with the pictures. http://www.chladnis-heirs.com/special-nwa6022.html Well. We issued really a lot of different Rumurutiites the recent years, but one like that one, we haven't seen yet - have you? A very unique appeal. That very distinct and constantly thick weathering frame all around. That grayish-brown matrix, with the orange freckles everywhere. Unbrecciated. Chondrules - it is classified as an R4. And here and there these huge inclusions, sometimes alabaster sometimes somewhat pink, as if they would be borrowed from a bencubbinite. Very interesting material, isn't it? One could suppose that this strange appeal may be phenomena of extensive weathering, but it isn't - as with W2/3 NWA 6022 is slightly fresher than the average. As we - and most probably you neither - haven't seen such an R before and so far, we guess, that it must be unpaired. Alas. Spectacular it is. So let's keep the Special even more special. The R-chondrite-prices everywhere you know - we say simply and despite these unique appearance: 20$ per gram (and both Chladni's Heirs have a bet running, how quickly this special will have been sold out :-) And an addendum we have. You might remember the very fine, fresher and affordable brachinite, NWA 6349, form the last but one special. There we were asked, whether we couldn't cut also some smaller slices. So we prepared also some very good budget pieces - at the same price per gram like the large ones. Here you are: http://www.chladnis-heirs.com/special-nwa6349-2.html Best wishes!

[meteorite-list] AD: Special: Gemmology of Vesta - Blossoms of Planetary Poetry
Dear Passionates, today we make something different than usual - curious as we are, we want to test whether facebook could be something for us and launched our special offer there. For the impatient ones - here already the link: http://kuerzer.de/VestaGems But don't worry, if you're not familiar with or if facebook is suspect to you, just give us a note, and we immediately will send you a private email with pictures prices of all available specimens. For that experiment we chose quite the most fabulous material which was readily prepared at hand. A few of you will remember our NWA 5478. That incredible eucrite with such a diversity of appearances, from a perfect Moon mimicry, to patterns you rather would expect on the catwalks of Paris or Milano, up to picture puzzles of fine art: http://www.chladnis-heirs.com/euc-face.jpg We were lucky to gather a longer while ago a few marbles of this material more. Or to say it like it should be correct: Some stones which we personally strongly believe to be paired to NWA 5478. Of course they will be correctly classified and they will obtain an own NWA-number. In fact we rather would have waited until we got the number, before we'd think about setting them on sale, but when we showed that specimen: http://www.chladnis-heirs.com/1_062gb.jpg ..the collectors urged us to offer them already in advance. We always sincerely hoped to get one day a larger stone of that material, without doubts such a specimen would be from the beginning on: legend. Alas, three years waiting yielded nothing more than these few pebbles, less than a small handful. If you keep in mind, that on a find site or in a strewnfield always the largest stones are picked up first and the smallest found last, we're not confident that our dream ever will come true. However. As small as the marbles are, it is certainly one of the finest HEDs, the deserts ever spat out. 23 specimens we have for sale. All are true astonishing gems. All are polished half-stones. The price per gram is higher than for average eucrites, but because the weights of the gems are so small, the overall-prices for the specimens are very comfortable. They rank between 51$ and 180$ per piece, two are larger and cost 500$ and 700$. Only with the best specimen of the whole new series we will make an exception, and will have a kind of an private auction without hurry. Highest bid will fetch it, increments are 10$, Secret maximum bids remain secret and will automatically used only to that extent necessary to hold the leading bid. http://www.chladnis-heirs.com/1_062gb.jpg And that, until nobody wants to bid more. With fair warnings. Hence without battles in the last 10 seconds. We're quite in the beginning at 90$ now. Duration - a day will be enough, but also necessary, for the Japanese and Australian collectors having a chance too. So again, Don't be shy to ask us for an email, if you don't like facebook. Alone the pictures you HAVE to see, they are a delight. Have all a fine and relaxing Sunday!

[meteorite-list] AD: The Pearls of the Vestals - Budget pieces
Dear list, Normally we hardly advertise a meteorite twice, but this time we want to give you a short note, because we hadn't set up a Special like usually - in general we wait for the NWA-number first, though when we had shown samples of this meteorite, the collectors didn't want to wait. And first and foremost, because this meteorite after our fancy, regarding its beauty and the huge variety of its forms of appearances, the cut stones offer, belongs to the most outstanding eucrites of our times. It's about the supposed NWA 5478-pairing from recently. After almost the whole load was sold out within one day, Stefan expertly prepared the remaining marbles we had left. Small half-stones, and the second course now, could be of special interest for the collector with limited budget, as the pieces rank between 20 and 60$ - many of them already gone too. (And for those aiming for highlights for their collections: the main mass stone, cut into halves is still available too). Despite the weights being small, we believe the specimens to be very use- and meaningful for any collector, as they show such an overabundance of amazing details and uncommon features, and aesthetically seen, they a true jewels. Well, and to whom that all sounds somewhat too elated, let's say it more soberly: If from 41 specimens, 32 are gone in 2 days - then that eucrite and that offer must have something.. So, just for feeling not responsible, for someone missing out on, we just wanted to give that quick reminder. If you're interested in, please send us an email, and we will send back the details about the pieces still left. (and if you ever wanted to know, why Vesta is a goddess? - You'll do so :-) Thank you for your attention, And have a fine Sunday.

[meteorite-list] Your Strong Presence in the Solar System
Hello all, and one thing you should not forget, so surprisingly it may sound for the one or the other: You all here on the list are actively taking part in and grandly supporting the exploration of our Solar System, either in hunting samples of the celestial bodies of our Solar System or enabling with your purchases of your collection specimens the work of the prominent and of the anonymous hunters. You're building up the backbone of earthbound planetology - and that more than ever. Your enthusiasm for the rocks of space and your hand-tight money spent grant that all these samples and materials are and steadily become available for science. Those samples, which mankind with its technical and financial means cannot retrieve else and which allow a more profound, much broader and detailed research on the history and compositions of the bodies of the Solar System than remote sensoring with space probes and in situ work with landers and rovers allow. Let's all hope, that this awareness wins recognition also in those countries, which are about or already have abandoned that most low-cost, but in the same place extremely efficient form of planetary research and exploration of the Solar system in taking away the legal preconditions necessary that those materials can be found at all. Let us take the opportunity to portend the next set of brand-new abstracts with new data and results about our recent Martian meteorites; Stones, which never could have been found without the help of the collectors, the tireless dedication of the anonymous hunters in Sahara and the support of the scientists.

Re: [meteorite-list] Help with Kunya-Urgench
Hi Henry and Gary, in my opinion this specimen is definitely no Kunya-Urgench. In principle Kunya-Urgench, if fresh, is of a light-grey to witish appearance. But Kunya seemed to have to be exposed to humidity on the place of fall, so that it has more or less very often hefty stainings from rust. Kunya was a large mass - the second largest stone meteorites in existence. Scattered around the impact pit were collected hundreds of small and smallest fragments and a few larger ones. Some of the hunters, who collected them, are here also on the list. The small fragmets, usually in the weight range form 1-10 grams, are almost all very oxidized, but nevertheless some show here and there still some fresh corners. The larger ones (like necessary for having such a cut like Henry has)are often somewhat better preserved. The clean ones are withish grey mottled with tiny brown and ochre rust spots, the somewhat more oxidized ones, have larger areas of rust. But all have still parts of the original fresh matrix preserved. Here some examples of various degrees of oxidation of Kunya. http://www.thetricottetcollection.com/met_kunyaurgench.html http://www.meteoritelabels.com/images/Kunya.jpg http://www.meteorite-martin.de/images/meteor/kunyaurgench.jpg Henry's specimen display a fully oxidized matrix, hence it is an old and weathered chondrite, which certainly doesn't belong to the fall of Kunya-Urgench. I'd recommend to return it to the seller. Best!

[meteorite-list] AD: Short Note - Last 6 small pieces of the sensational NWA 6162 prov. Martian
Dear list members, reading Ron's last posting below, it seems, that in some years we'll get some competition by NASA and ESA. Was already there, Said the hedgehog to the hare... Now seriously, we're about to distribute the very last six samples of the best shergottite. When they'll be gone, then NWA 6162 prov. unfortunately will be already history. To try to do justice to that material in a hyperventilating staccato of superlatives would fail, just click instead on these pictures given in this link again to get a vague impression. http://www.rocksfromspace.org/June_12_2010.html It is stunning and it is breathtaking. Ask those, who already have their specimen home or in the lab. The only alternatives of comparable freshness among the shergottites to NWA 6162 are Zagami and Shergotty. But NWA 6162 is somewhat more eye-appealing. I hope we have now supplied all Martian-complete-collectors. These are the last 3 grams of the 89g stone. We currently have 5 partslices left - all with a long fusion-crusted edge: 0.290g 0.398g 0.415g 0.437g 0.450g As well as a partial endcut with especially much of the fantastic crust 0.916g Email for (moderate) prices and pictures. And don't forget to take a look to the Western evening sky and the planetary theatre we have these days there going on; also to see, where your specimen really comes from!

The costly mission would blast off on an Atlas 5 rocket in 2018 and land two rovers on Mars with a single sky crane descent system that will be tested for the first time at the Red Planet in August 2012. It would be the first time two rovers will be delivered to the same landing site on Mars. The European Space Agency's ExoMars rover and a $2 billion NASA Mars Astrobiology Explorer-Cacher mission are the leading candidates for the tandem project. ExoMars carries a drill to burrow into the Mars subsurface and retrieve samples from as deep as six feet underground. Some of that soil could be placed inside a high-tech storage device on NASA's rover for eventual return to Earth, according to Doug McCuistion, head of the agency's Mars exploration program. There may be a possibility to actually cache subsurface samples that the ExoMars drill collects, which had not been in our plans before, McCuistion said in an interview last week. Marcello Coradini, ESA's coordinator for solar system missions, confirmed the studies of placing underground samples into a NASA cache for later retrieval. We're hoping that what we do with our rover is actually collect the samples that we will then go back in the 2020s to retrieve in the Mars sample return campaign, McCuistion said. A simple sample cache was originally planned for NASA's Mars Science Laboratory launching next year, but officials removed the payload due to scientific and technical concerns, according to McCuistion. Spacecraft traveling from Earth to Mars can only launch about every 26 months, limiting sample return options. Scientists agree the best strategy is to spread the effort across three missions to spread the high cost of the endeavor among several years. By breaking it up into those three pieces, you can sort of thread the costs and spread some of the risks over multiple missions and make the overall program both more robust and more affordable, said Steve Squyres, a Cornell University researcher leading an independent review of potential NASA science missions. Called the decadal survey, the review will rank the scientific value of 28 proposed missions for the next 10 years. The ultimate timing of a sample return campaign will boil down to the budget of both NASA and ESA, McCuistion said. David Southwood, ESA's director of science and robotic exploration, said kicking off a sample return campaign by 2020 would mean going above the 200 million (euros) a year we're assuming as a steady-state (budget) in the late part of this decade. Squyres said the decadal survey will attempt to settle on an estimated total cost for three sample return missions. Recent cost projections have pegged the effort's total price at more than $5 billion. (The sample return missions) could be spaced as close as close
Re: [meteorite-list] Rocks from Space Picture of the Day - August 24, 2010
Hi Richard, Chladnite is a synonym for enstatite and was a synonym for the aubrites among the meteorites. That mineral name was introduced by Charles U. Shepard (1804-1886) in 1846 when he firstly observed enstatite in the 1843 fallen Bishopville aubrite, to honor Ernst Florens Friedrich Chladni as the founder of modern meteoritics. Best!

(1986) Cosmic Debris, Meteorites in History, Chapter 4, p. 121: Chladnite: Again, it was an observation by Charles U. Shepard that paved the way toward the identification of the pyroxenes. In 1846 he described a mineral which, he wrote, is a ter-silicate of magnesia...[and] forms more than two-thirds of the Bishopville stone. He named the mineral chladnite in honor of Chladni, the scientific founder of this department of knowledge. Two years later Shepard reported his analytical results: 70 percent silicic acid, 28 percent magnesia, and 1 percent soda, so that the ratio of oxygen in the magnesia to that in the silica was 1 to 3. In 1851 Sartorius von Waltershausen analyzed a fragment of the Bishopville meteorite and arrived at about the same results, but also found 1.5 percent alumina. Though making errors in his calculations, Sartorius did produce the correct formula - MgO,SiO2; however, he postulated that chladnite was a kind of wollastonite, in which magnesia substituted for lime. The issue was confused further in 1861, when Rammelsberg found by analysis almost 3 percent alumina, 35 percent magnesia, and only 57.5 percent silicic acid. Doubting the existence of a definite mineral, Rammelsberg did not attempt to devise a chemical formula. Meanwhile, Shepard in 1854 described the Tucson iron meteorite and speculated that certain inclusions were chladnite. J. Lawrence Smith immediately corrected him, pointing out that the inclusions were actually olivine, and added a note that he suspected chladnite is likely to prove a pyroxene. At about the same time, in 1855, Gustav A. Kenngott, professor of mineralogy at Zurich, published a memoir giving details of the minerals of what he termed the augite group of the pyroxenes. One member of the group was enstatite, which, Kenngott wrote, was a bisilicate of magnesia, was augitic in crystallization, and had the formula 3MgO,2SiO3. In 1861, when Kenngott saw Rammelsberg's analysis of chladnite, he insisted that the mineral was identical with enstatite. Smith then made two analyses of the Bishopville meteorite and reported in 1864 that chladnite consisted of 60 percent silica and nearly 40 percent magnesia. He agreed with Kenngott that the mineral was the magnesian pyroxene, enstatite, and accepted Kenngott's formula, in which the oxygen content of the magnesia to that of the silica was 1 to 2. Both Rammelsberg and Maskelyne acted to clarify the formula of enstatite, and through his work on the Breitenbach, Bustee, and Manegaon meteorites, Maskelyne recognized the existence of solid-solution series that included enstatite and bronzite. By the 1870s mineralogists began to report regularly these constituents in meteorites. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] AD: Special: A New, unusual and Unbrecciated Aubrite! NWA 6350 prov
Dear collectors and meteoricists, after a long time, we are back with one of our Specials, which became necessary, as this time we want to introduce a stone, where it's difficult to avoid the so worn-out term: Sensational. NWA 6350 provisional- A new aubrite. If you follow us, in checking the Meteoritical Bulletin database, you'll understand, why this find has such a special meaning for us. The database is still somewhat biased, as the numerous El Haggouina-pairings there aren't changed from AUB to EL yet. (And with them we personally follow Bunch, Wittke, Irving et al. that El Haggouina is an EL). So the first true aubrite in the list there, should be NWA 4799. You remember, it was introduced here on the list, the very uncommon highly brecciated one. To what extent NWA 4832/4871 are belonging to NWA 4799, that we don't know yet; David Weir lists 4871 as a pairing of NWA 4799 Find them here, also a wonderful resource of information, on the meteorite pages of NAU: http://www4.nau.edu/meteorite/Meteorite/Aubrite.html For NWA 5419 zero information is available, therefore not yet clear in which context it belongs. Well, and the second real aubrite was NWA 5217. NWA 6350 is paired to it. Therefore, from 2 decades of desert hunt in Sahara and 1 decade in Oman, we have so far most probably only two different aubrites at all. And aubrites are the most difficult discipline, it seems much more easier to find a lunaite or even a nakhlite. Hence, we choose in the title several attributes: Unbrecciated we wrote, to show, that it is not paired with NWA 4799. Fresh we could have added, not only because NWA 6350 is relatively well preserved, but to signal, that it isn't just another El Hagg. But why we said New? NWA 5217 was a small stone of 40grams. It is listed in the Bulletin to be at an Anonymous. Never we saw it offered - with NWA 6350 for the first time this exciting material will be available for the collector. Unusual: NWA 6350/5217 as well as NWA 4799 are important finds. They both are distinct from the other aubrites. Let us simply quote from that short abstract: http://www.lpi.usra.edu/meetings/metsoc2008/pdf/5309.pdf The high temperature igneous cumulate characteristics of NWA 4799 and 5217 are unique among aubrites. Moreover, the complex mineralogy of NWA 5217 is remarkable and distinctive. Because these aubrites appear to be igneous cumulates and not derived from shock melts, they likely formed in a fairly large parent body rather than a small asteroid (such as main belt E asteroids and the NEO E asteroid 3103 Eger [2]). And now in medias res. NWA 6350 was unfortunately also of a very small tkw. 50grams the stone only had. The number of available specimens is so limited, that by far we wouldn't be able to satisfy the needs of even only our truest collectors and customers. Therefore we decided to set all pieces here on the list, for everyone allowing the chance to get one equally. We hope you don't mind, that we made an exception and had let David Weir to pick a specimen in advance, because his fantastic Meteorite Studies are such an enormous service to the meteorite world, that we think, that he deserves all support to keep his studies complete. And - science first - one of the partial endcuts is temporary on hold for an institute. Although, as a cumulate one, its relative freshness and its tiny tkw, we kept the prices with 60-100$/g still partially in the Pena Blanca Spring range. That Norton County can be had cheaper, is explained, also to the historics collector, well by this hilarious photo: http://kuerzer.de/Aubpaz Usually, whenever we announce a novelty of such a caliber, quite a rush of emails comes over us. It would be extremely helpful, if you would send us a ranking of the specimens you desire, to grant a fast and chronologically course. Now - long enough we kept you on the tenterhooks. Here they are: http://www.chladnis-heirs.com/special-nwa6350.html Let the games begin!

Re: [meteorite-list] AD: Unbrecciated Aubrite! NWA 6350 prov Shallowater......
Hi Greg, many thanks for the congrats! Of course, 34 years Antarctic campaigns and only 2 different aubrites found there; 20 years Sahara and 10 years Oman, also only 2 different aubrites... But not only due this absurd rareness, that little stone is in our internal VIP-meteorite-ranking settled quite near the top, it's moreover the characteristics of the material itself! We confess, that our Ad was a little bit inapt, as probably only the experts recognized immediately, what we have there. In fact it would have been easier and sufficient, just to write two catchphrases: UNBRECCIATEDSHALLOWATER You know, ALL aubrites were so far heftily brecciated, destroyed, shocked, annealed, partially molten, partially morphed and metamorphed, brecciated, brecciated and brecciated - with all the implications about their precursor material, - El Haggouina's initially misclassification was no accident, melt an E-chondrite and you get out something very similar to an aubrite - and their possible parent bodies, small, large, differentiated, chondritic, catastrophic collisions, regolith formation,... in space one is looking, Steins or the Hungaria-Family ect. pp. ALL but one. Shallowater! The one and only originally preserved aubrite - the unbrecciated one. And Shallowater was s alone. So alone, that in former times, it got even a suffix -an added behind the AUB: Now Shallowater got a little sister and a little brother: NWA 5217/6350. And it's amazing. We read, that the little enstatites in Shallowater hadn't grown randomly in all directions, but they show a preferred orientation, which means they grew under gravitational influence - which in turn means, that the parent body have had to be fairly large. 100km. It's always astonishing, what you can read out from such a little stone. See, Shallowater looks in several ways similar to NWA 6350. TCU-specimen, photo Geoff Notkin: http://tin.er.usgs.gov/meteor/get_original_photo.php?recno=5637847 Close-up - Hey Madame Anne has just two Shallowaters for sale! (It's fairlyvery difficult to get any.) http://www.impactika.com/catpix/AA043.jpg Small slice, we had once: http://www.chladnis-heirs.com/shallowater-0.455g.jpg ...if you'd ask us, we would say, that NWA 6350 is maybe a slight idea fresher than Shallowater. (and it seems to be mineralogically also somewhat more interesting, but the research isn't finished yet). Well, and there we see it, even the most inveterate historics collector has to admit, in what for meteoritically happy fantastic years we're living right now! And again and again we can't only appeal and pray for reason among the responsible persons, that they keep the deserts open!! For such stones, see Antarctica, see NWA, see Dho you need terrific large find numbers, until once such a find will be among them. And really most researchers don't want to play only with a handful of weathered new L6s or H5s a year. MetSoc, scientists, collectors, curators - we all need your help, that we won't destroy for ourselves all that, what we so laboriously, but also so fantastically have built up these years. It's only a pity, that NWA 5217 wasn't available and that NWA 6350 was such a small stone too. So to collectively answer all requests, it's sold out. Though - cause it's a little bit unfair, that we explained the stone now a little better: There is still HOPE! We still wait for the final o.k. by a researcher, for whom we had reserved the 12.5g partial endcut: http://www.chladnis-heirs.com/nwa6350-12.506g-end.JPG http://www.chladnis-heirs.com/nwa6350-12.506g-end-2.JPG We can't promise anything right now, because politeness requires to wait still some days more, but maybe maybe it will be free again and available. So it's possible to secure an option on it, for that case. At 60$/g - a tenth of the Shallowater price. Desert made it possible. All the best!

Dear meteorite enthusiasts, Today we release already the next stunning Special. The differences and relations between PACs, 7ers and metachondrites were already once in detail discussed here on the list, - for those not remembering so well, we like always recommend David Weirs Meteorite Studies: http://www.meteoritestudies.com/ Therefore this Special and this new meteorite doesnt require a such verbose introduction like usually. So far there were LL-, H-, CM- and CR-metachondrites, funny enough L-metachondrites were still missing. With NWA 6348 prov. we announce: Mission accomplished. NWA 6348 was one stone, found this year, with a weight of 136g. Averagely shocked with S3, nevertheless displaying various shock zones and veins, and with W2 somewhat less weathered than the average. Here you have all specimens. Prices: 50$/g for the small polished slices from 3g to 10g. 40$/g for specimens 10g.

Re: [meteorite-list] metachondrite
Hi Steve, no.. a metachondrite is a chondrite without chondrules :-) The meta comes from metamorph. A metamorphosis means, that a rock is changed in its structure or its composition into a different rock, but remaining in a solid state, while this happens. This change can be caused by different agents, like heat, pressure, liquids or contact with other rocks. Well, with the metachondrites (or 7ers or PACs, where they were/are sorted in too) their chemistry and their isotopes are similar with or the same as the respective chondrite groups. L-metachondrites with L; H-metachondrites with H, LL-...ect. Though - they are free of chondrules. But: they show evidence of recrystallization and in some of these stones of that kind, one finds remainders left and relicts, which once were chondrules. Therefore it's clear, they were once chondrites (of the respective groups H, LL, CV, CR now with NWA 6348 the first one, named to come from the L-group) and they are directly derived from the chondrites. So. With the chondrites, you have always those numbers behind the H, L, ect. - the petrological grade. 3,4,5,6. In the type-3 chondrites, you have the full garden of these funny balls called chondrules, sharply defined sitting in the matrix. If you heat now the affair, the crystal growing will take place, and from the 4, to 5, to the 6ers the chondrules and the matrix are more and more grown together, the chondrules get less sharper defined, they got often also more sparsely. And a second thing happens, the constituents of such a 3er, they are chemically and physically different from each other. But like all in universe, they want to be balanced, they desire an equilibrium. If you heat now such a rock, the ions can roam in the rock. And the constituents start to assimilate to each other or to get in a chemical balance. So the type-3 chondrites are those, which were least heated and are the most unchanged preserved once. Called unequilibrated, while from type 4 on they are called equilibrated. Well. So the chondrites evolve and are more and more changed from type-3 to type 6. But with the new finds from the deserts, we got some rocks, which showed, that type 6 is not the end! That there are also chondrites, which were more heated or were that process continued - so that in the end they had lost all their chondrules, and got the most equilibrated ones and fully recrystallized. Two main heat sources you have for such parent bodies. Heating due impacts, where the kinetic energy of the impactor is relieved in deformation of the target rock and heat. The other one is after the formation of such a celestial body, the radioactive decay of its instable and heavy elements. The larger such a body is, the more of that stuff it has, the hotter it can get - up to the complete melting of the body. And the larger such an body is the longer it can keep the heat - Earth e.g. is large enough, that it was quite still warm down there, where the Chilean miners were sitting. Impacts, you know what happens, if the smack is hefty, then the rock beneath simply melts - making these IMB, impact melt breccias meteorites, usually quite black, homogenous and with textureless glasses.. The metachondrites are different from them. If you take that idea with that heating by decay, then you can suppose, that they once sat more deeper, closer to the core of their parent body than the 3ers, 4ers,... where it got hotter and where it was longer hot. Now, cause 6 was obviously not the end, Dodd in the 1970ies thought it is necessary to have also a 7. Problem: Most of these crazy stones have no chondrules left. Therefore some say: A chondrite is called a chondrite because it has chondrules! A stone, that has no chondrules has to be called: achondrite!! Therfore a 7er-chondrite would be per definition not allowed. And because the stuff is directly derived from chondrites, which are the most primitive matter we have, we put these stones into the group, we already have, where the ACAPs, LODs, WINs are already sitting in and call them primitive achondrites. And that is somewhat unhappy. Achondrites we have all that stuff from differentiated, non-chondritic parent bodies, like the Vesta matters eucrites, diogenites, howardites, but also the aubrites, ureilites, brachinites, angrites, Martians, Lunars... But from these stones, we know exactly from their composition that they were chondrites. And primitive doesn't fit so well neither - because they aren't that primitive but among the chondrites the most metamorph, most evolved, most equilibrated ones of all. And they are not an unchanged primary meteorite, they are a product of them. The opposite of primitive. The term Metachondrite is there more exact, it says: Look I was a chondrite - I am a metamorph chondrite. So in the name the genesis of the rock is already visible. And it allows to be more specific, as one hasn't to lump all these rocks, from ACAPs, WINs and all these diverse ex-chondrites
Re: [meteorite-list] metachondrite
chondrule outlines sometimes persist. The new term metachondrite has not been defined in the formal literature, but it seems to overlap with what I would call the high end of type 6 and primitive achondrites. I think Ted Bunch reads this list, so he can chime in if this is not correct. Personally, I see no benefit to this term, as I am comfortable calling those with chondritic compositions type 6 chondrites, and I am uncomfortable calling those which have differentiated chondrites, even with the prefix meta-.

[meteorite-list] AD: Special: New uncommon Martian meteorite - NWA 6710 prov.
Good Day meteorite and planetary lovers, Proudly we announce, that our next Martian has arrived, is sliced and grinded already and waits now for flying into your collection! NWA 6710 (provisional) will be its name and according the newer more systematic nomenclature it is a Intermediate Permafic Olivine-Phyric Shergottite. Already a first glance reveals, that NWA 6710 doesnt meet the usual viewing habits for shergottites and that it must be in several aspects a fairly uncommon material. We see a matrix of very fresh appearance, which is so incredibly fine-grained that macroscopically it almost looks uniformly. Very sparsely we find a few patches of dark maskelynite, though the clou of this Martian is: Over and over it is peppered with fine olivines of an intensive pastel green! An amazing stone. The planetary connoisseur is immediately aware: there is only one such Martian it has to be a pairing of NWA 2990. This grouplet consist of four members; NWA 2990, NWA 5960, NWA 6234 and now NWA 6710. NWA 2990 is long ago gone. NWA 5960 had a tragic fate, the main mass was stolen in mail (a fate, which makes us all angry as it happened by such a stupidity. Such a stone is absolutely unsalable for any thief and it is the rarest matter on the globe, almost irreplaceable. Please alert us or the owner immediately for the case, that such material will be offered to you). And NWA 6234 seems already to be sold out too. The characteristics of the entire stones were, that they are covered with a very green skin. Only NWA 2990 had one side with a good black fusion crust, while NWA 5960 and NWA 6234 were naked. Not so our new NWA 6710, it has some dark fusion crust left, but worn and not so fine preserved as with NWA 2990. Internally all stones are very fresh. NWA 6710 prov. has a tkw of 74 grams. Astonishingly few is published yet about the NWA 2990-group, we think, that will change now with the recent finds.

Hello Martin, Congrats on the NWA 6710 Martian! I am saddened to hear about the stolen NWA 5960 pairing. I only just heard about this today and here through your announcement. What was the weight of 5960? I heard who the stone was shipped to and who the Moroccan dealer is. If this is a clear-cut case of theft by the recipient, then that person's name should be made known to all dealers, collectors and police if possible. I do not know any details, you know more than I do and I am sure you are helping the Moroccan dealer who was ripped off either by the shipping company or the recipient. This kind of behavior should not be tolerated. I hope the thief, whoever it is, finds a conscience and sends the stone back to the rightful owner! In the possibility that it got lost in shipping by the carrier, lets hope the wayward package, with stone, finds its way to the recipient or back to the Moroccan owner!

Good Day meteorite and planetary lovers, Proudly we announce, that our next Martian has arrived, is sliced and grinded already and waits now for flying into your collection! NWA 6710 (provisional) will be its name and according the newer more systematic nomenclature it is a Intermediate Permafic Olivine-Phyric Shergottite. Already a first glance reveals, that NWA 6710 doesn’t meet the usual viewing habits for shergottites and that it must be in several aspects a fairly uncommon material. We see a matrix of very fresh appearance, which is so incredibly fine-grained that macroscopically it almost looks uniformly. Very sparsely we find a few patches of dark maskelynite, though the clou of this Martian is: Over and over it is peppered with fine olivines of an intensive pastel green! An amazing stone. The planetary connoisseur is immediately aware: there is only one such Martian – it has to be a pairing of NWA 2990. This grouplet consist of four members; NWA 2990, NWA 5960, NWA 6234 and now NWA 6710. NWA 2990 is long ago gone. NWA 5960 had a tragic fate, the main mass was stolen in mail (a fate, which makes us all angry as it happened by such a stupidity. Such a stone is absolutely unsalable for any thief and it is the rarest matter on the globe, almost irreplaceable. Please alert us or the owner immediately for the case, that such material will be offered to you). And NWA 6234 seems already to be sold out too. The characteristics of the entire stones were, that they are covered with a very green skin. Only NWA 2990 had one side with a good black fusion crust, while NWA 5960 and NWA 6234 were naked. Not so our new NWA 6710, it has some dark fusion crust left, but worn and not so fine preserved as with NWA 2990. Internally all stones are very fresh. NWA 6710 prov. has a tkw of 74 grams. Astonishingly few is published yet about the NWA 2990-group, we think, that will change now with the recent finds. So that we can refer you at the moment only to the introductory paper for NWA 2990 from two years ago, where you can find the essential details about this uncommon Mars rock: T. E. Bunch, A. J.

[meteorite-list] AD: Special: NWA 6826 - the Best Karoonda-Chondrite Chladni's Heirs ever had
Dear meteorite lovers and experts, one of the grand specialties of Chladni's Heirs are the CK-Chondrites. Still this year, we will receive the number for our 20th CK, all among each other unpaired - as many as nobody else had in that time span. Nevertheless the CK-chondrites remain rarer than any CV, CO or any eucrite, diogenite and howardite. Today, we have the honor and the joy to introduce to you, that CK, which we consider the best CK of all we ever had: NWA 6826. Here already for the most hasty ones, the specimens! http://www.chladnis-heirs.com/specials/special-nwa6826.html Much we explained about the CK-group in our former Specials, their genetic relation to the CV and CO-group, their differences to these types and about the characteristics, which make the CK-group so interesting and fascinating. With NWA 6826 today, we will abstain from lengthy explanations and iterations, (in case Weir's Studies will help you) because the beauty of this very material touches the heart of every collector. Time it is - that we learned from many of our CKs, and now this very NWA 6824 is the most incontrovertible argument for that - to rewrite the old books, which disqualify the CKs as dull, chondrules- ad CAI-poor and featureless, due to their sulphides and iron-oxides and shock-blackening. (Probably they had only Kobe, Karoonda and old HaH 280/281 at hand). NWA 6826 speaks a different language! It demonstrates par excellence how vivid, busy and spectacular CKs can be, displaying a huge variety of different details. Absolutely NECESSARY for you to get, what we're talking about, is TO ENLARGE THE THUMBNAIL PHOTOS by clicking, to fully enjoy that extravaganza and not missing out by skimming quickly the page. NWA 6824 is weakly shocked with S2. And it is very fresh and unweathered with a weathering grade of W1. We had also even slightly fresher ones, W0/1 among our palette of CKs, though they were not so dazzling like this jewel now. Note also the great snakeskin of fusion crust on the backside of the endcuts: http://www.chladnis-heirs.com/specials/nwa6826-688.5g-end3.JPG Well, you might be worried about the costs for such an overwhelming material, and finally our Moroccan friends and colleagues raised the issue here on the list of the dramatically changed situation, which is going to happen since a longer while in the NWA-scene. But - we are proud to tell you, that we decided to make today an offer, which regarding the quality, should beat out the price levels, which you are used to commonly see for the CK-group; and priced all specimens - from the centerpiece of your carbonaceous-section to the meaningful reference partslice, all grinded and polished, at one price, a reference to the Golden Times of NWA of 25$/g. With a tkw of 1.3kg we hope, that nobody has to miss out and we can launch this Special earlier than usually. Nevertheless, as always, it would be very helpful, if you would send us a wish-list with the ranking of your desired specimens, to avoid delays and traffic jam. Once again, here they are now: http://www.chladnis-heirs.com/specials/special-nwa6826.html Enjoy!

[meteorite-list] AD: Special: Multicolor Ragland-like Chondrules-Galore - NWA 6864 L3.4
Dear collector-friends, back from the Ensisheim fair, we're thinking, what we could offer as a consolation for those, who had to stay home and are now longingly watching the pictures of the show. So we were pondering, and picked for our little Special a brand-new unequilibrated L-chondrite: NWA 6864. Here you are, after a longer absence of 3ers among our specials - a really pretty one, isn't it? http://www.chladnis-heirs.com/specials/special-nwa6864.html Look how densely the chondrules are sitting together in this meteorite. All sizes, from sparse giants to tiniest dwarves, freely mixed in a happy clutter. With W2 somewhat fresher than the average. But the main eye-catchers are - exactly: The Colors! The full spectrum is given by the colors of the individual chondrules. This L3.4 strongly resembles historic Ragland, we even think, that it is a slight idea more beautiful (biased as our taste is). Affordable it is, slices for every purse available. Just the right stone at the right moment. A very fine unequlibrated chondrite, of a special aesthetics, containing the germs for our planets - not only for the chondrules-lovers. Just Enjoy!

[meteorite-list] AD: Special: Truly baffling sensational Howardite - NWA 6709 - absolutely stunning and very fresh.
Dear meteorite community, with this Special we have to introduce to you an enormous oddity. It is about a HED-meteorite of a kind, which we hadn't ever seen before in our careers before. It came in two stones, one of them was covered with a lush fusion crust, wonderfully structured by thick and oriented flowlines. And in some parts, that very crust displayed a gloss and a shine, iridescent in all colours of the rainbow; an effect, reminding almost to bismuth! Please take a look to the photos, where we tried to captured the effect: http://www.chladnis-heirs.com/new-meteorites/nwa6709.html The interior was no less a riddle for us. The distribution and sizes of the various fragments and clasts were unlike we had seen in any polymict HED before. A variety of clasts is of a kind, like we never had recovered in any Vesta meteorite. Please take a closer look to the slices and you will share our surprise. And a very few of these clasts develope due to their microscopically lamellae-texture a fire like an opal, if turned around in the light. The response to a magnet is very inhomogeneous within the slices, although no differences are visible to the eye and all in all the interior has a somewhat dull yellowish tint - although the material is very fresh - and that tint and the circumstances made us initially think, it might be diogenitic. It is under classification at Dr. Anthony Irving and the values say, that it is a shocked howardite. We crafted now a set of polished sliced of all sizes, to share this exceptional material with you. Please acknowledge that we have kept the price, despite of the for us so unique properties of the material, well affordable, for everybody staying able to add a specimen of this truly exceptional stone to his collection. And an addition it is, also for the most experienced veteran collector. Earlier today we had published the Special in the German forum, therefore not so many specimens are left. For the largest slice we can offer a discount as it is the only one, which isn't coplanar. And finally, the specimen named piece #2, which we chose to illustrate best that rainbow-bismuth-gloss of the fusion crust on the first linked page, is available too. It weighs 119.2g and we're accepting offers.

[meteorite-list] Was Test - ignore - the meteorite collection in the Mysty Park, Interlaken
Hello, we were asked, what for a meteorite display it could be in that youtube-clip, we filled our test-posting with: http://www.youtube.com/watch?v=tHQn7VNLUJI These are the remainders of the once most important (and perhaps still most important) meteorite collection of Switzerland: The former collection of the Bally-Prior museum in Schoenenwerd, Canton Solothurn, (where Rolf Buehler was also curator - author of the still best meteorite book in German language). Bally-Prior was a fabricant of shoes. In the end the meteorite collection comprised 500 historic meteorites from more than 70 countries. The museum housed also one of the most important mineral collections of Switzerland. Was financed by an private foundation, but the museum went more or less bankrupt. To restore and to maintain the museum and the collections in the end a relatively modest amount was missing, approx 450.000$. A sum the Suisse state obviously wasn't willing to pay. So unbelievable but true: the mineral meteorite collections were dissolved and hawked 5-6 years ago! Museums and universities had a preemption to buy before the private collectors. All museums and universities failed in taking over the meteorite collection, even the ETH Zurich, whereto Bally-Prior had donated endless mineral specimens and whole collections. So afterwards a private person bought the meteorite collection. Maybe one can say, that with that failure to secure the Bally-Prior meteorite collection for the public and for research, Suisse meteorite history hit rock bottom. Only one similar grave case comes into our minds, the mistake not to have held Zeitschel's collection, once largest private collection in the World, in Germany - but that was in the 1980ies. The private buyer gave a part (most?) of the collection on loan to that place, where the video was taken. Well, maybe not an ideal place, but at least they are on display. It's a kind of a Disneyland once created by Europe's most famous ufologist, Erich von Daeniken. - the Mysty Park in Interlaken, Canton Bern. Side remark - we had these discussions about laws, meteorites as natural or cultural heritage (and a museum collection is for sure a cultural heritage in the terms of the UNESCO-Convention of 1970) etc. - Well, if one regards this case, doubts can rise, whether meteorites in Switzerland really are objects of cultural meaning, scientific importance and public interest and if the respective laws about such objects found can be applied on meteorites. Mistakes are made to learn from them.

[meteorite-list] AD: Unique and Uncommon new Martian - NWA 5990
Dear collectors, today it is highest time to introduce our new not only in our eyes quite sensational planetary recovery. NWA 5990. A new Martian, remarkably distinct from the so far known finds. Before cutting it was a relatively small stone of only 59 grams, coated with an unweathered black fusion crust with some indications of flight marks, which seemed to have spalled of on one corner by impacting the ground. The stone felt somewhat heavier than one would expect for a planetary one. Here you have a picture of the intact mass: http://www.chladnis-heirs.com/uncut-mainm-klein.jpg The first cut then revealed the outstanding nature of that small stone. The overall fresh appearance of the exterior was trumped by the pristinely looking cross section and you may comprehend our sudden elatedness, if you take a look at this picture of the unpolished cut surface: http://www.chladnis-heirs.com/6.995g-end-kl.jpg As you can see, that stone looks simply different from all other Martians we know. Well, with the numerous partially blackened olivines, one could tend to think into the direction of a lherzolithe, but it turned out, that the stone contains by far too much plagioclase to be lherzolithic. The grain size however fits to a diabase. That material is currently under analyses with a high priority at Dr.Irving, Dr.Herd et al. - and perhaps as early as in January an abstract will be already available. Therefore we beg for your understanding, that we can't forecast the exciting results, but have to leave the first publication to the researchers, avidly working on that surprising material. Maybe the one or other being already the proud owner of a slice will share his/her observations here in this thread with us instead. And here starts our dilemma - you may wonder, why we go public with this new Martian already without being able to name and explain the particularities and specifics of this new material - especially so shortly before a paper is scheduled; also it is planned to introduce the stone at the next Lunar Planetary Science Conference in Houston in beginning March.. Well the reason is simple - until then the material will have been completely gone and you would have to miss out that important new Martian. As the tkw was so low and this unique meteorite has such a scientific brisance, we had of course to address firstly to research institutes, like we had to do with NWA 5789 too. Afterwards we supplied the Martian enthusiasts from our address book (and we cordially recommend and invite the planetary specialists to contact us, if they want to be added there too). So in the end and at present there are only two specimens left! Half a fullslice with fusion crust. 2.338g Price is 1600$/g http://www.chladnis-heirs.com/2_338g.jpg And a crusted partial endcut. 1.908g at 1500$/g http://www.chladnis-heirs.com/1_908g_endcut.jpg http://www.chladnis-heirs.com/1_908g-end2.jpg Else there would be only these two pieces, but they are on hold for a museum, the negotiations aren't finished yet. So most probably they won't be available. A cap of the stone with a lot of crust and flight marks. (Largest intact piece, hence depending on definitions the main mass): http://www.chladnis-heirs.com/6.955g-end2-kl.jpg http://www.chladnis-heirs.com/6.995g-end-kl.jpg And a partslice. http://www.chladnis-heirs.com/2_055g.jpg If these specimens will have been gone, not a single grain of the stone will remain available.

Re: [meteorite-list] AD: Unique Martian NWA 5990 - Smaller Pieces desired?
Good Afternoon list, we received several emails with list-members expressing their disappointment or sadness that they'd not able to add this really exciting Martian material to their collection, because the offered specimens are somewhat too mighty. Aye, it's a dilemma. We had almost no small cuts, neither many crumbs broke loose while cutting and on the other hand, with such important material of such a low tkw, we feel always somewhat guilty, if we produce too much cut loss. Indeed it is somewhat unfair.. Well, in a Christmassy mood, what do you think about the idea, to sacrifice one slice, in cutting it down to more budget-friendly servings? A kind of a pool - if enough collectors will raise their fingers, so that a complete slice can be moved, we could slaughter it, perhaps with a 100/g spread to compensate the cut loss and the pain. That said (and of course having in mind, that it's quite the most inadequate time of the year for offering such a bomb - but most of you know our often liberal payment policy), just send a PM and we will see and try our best.

Re: [meteorite-list] Ordinary chondrites - rarest to the most common classes
Indeed, it's for the first time, that I read that R-chondrites are included in the OC-group. If so, why exactly them and not the K-chondrites, the Carbonaceous from grade 3-6, the ungrouped and the enstatite chondrites too? valuable type of OC from a scientific perspective is petrologic type 3.00-3.01 Where one has to say, that it's maybe too early to say that, Because the classification with decimal places, (even with two!), is a relatively new occurrence - most classifiers seems still to prefer to use a simple 3 - so that in case, there are still a lot known type-3ers awaiting to be revisited regarding the degree of their (un)equilibration. But I agree - Ordinary is a somewhat misleading term, - as the ordinary chondrites have told us most about the origin and formation of the solar system, the planets and ourselves, more than any iron or any lunar rock! Keep that always in mind, if you are tempted, now in the end of the desert-era and the decreed end of meteorite finding in so many countries, with all their weird and fancy exotic types, to wrinkle your nose about the ugly ordinary 25$-a-kilo-chunk from NWA-wonderland! Rare as brilliants they are - and they were our beginnings! Happy holidays to all! Martin -Ursprüngliche Nachricht- Von: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com] Im Auftrag von Jeff Grossman Gesendet: Mittwoch, 16. Dezember 2009 11:33 An: Meteorite-list Betreff: Re: [meteorite-list] Ordinary chondrites - rarest to the most common classes I agree with Doug... the rarest and most valuable type of OC from a scientific perspective is petrologic type 3.00-3.01, from any of the chemical groups. Only one is known... Semarkona. If we take a more expansive definition of ordinary chondrite than most of my rather conservative colleagues are normally willing to accept, I would say that the rarest group of OCs is the R chondrites (only ~100 are known and many of those are paired). In addition, a number of unique ungrouped meteorites are OC-like. But again, I don't know of any colleagues who agree with me that R chondrites are in the OC class. [I would say that the OC class has two clans, the H-L-LL clan and the R clan]. Jeff Mexicodoug wrote: Hi Melanie and thanks for the enthusiasm you add to the list ... Here's a high to low sorting of the ordinary chondrites, for over 32,000 meteorites: 22.0% L6 (most common) 19.9% H5 12.9% L5 12.3% H4 11.5% H6 7.8% LL5 4.2% LL6 3.3% L4 2.2% H3 2.0% L3 0.8% LL4 0.8% LL3 0.1% L7 0.1% LL7 0.03% H7 (least common) But this common and rare is a misleading label. That is a harder question if you look too closely at the deails and consider inhomogeneous and brecciated ordinary chondrites. That can all become somewhat unique if you ask the right person. Then there are the motley crew of ungrouped ordinary chondrites where it is hard to generalize. Some may be a weak classification while others might truly be weird (rare). Just a few notes: the H7, L7, LL7 types are not widely used in the literature and border on impact melts, so I'd take them with a grain of salt unless someone goes postal on me in which case they are right in whatever they say. The way I listed these, the meteorites are counted by the lowest number and won't show up in the higher thermal (metamorphosed) levels. In other words, for example, an LL3.8-6 is counted with the LL3's. If you have a special meteorite, it can sometimes be a rarer type if you start to split hairs, like H3.8 instead of just grouping it within the H3's, but there is some degree of arbitrariness to this. The tendency is that more virgin Solar system stuff (closer and closer 3.00) is more special and like a holy grail (rare in a sense) to some who study that - since it is more representative of the original material before water and heat were added and did their thing. From hat we can try to get the proof we need to work out early formation processes and theorize on the related dynamics happening. By this logic, and considering it is a very studied meteorite, the precious meteorite SEMARKONA (LL3.00 or is it 3.01 :-)), a witnessed fall from India, is rather unique being the only one with that 3.00 classification, which makes it super intact since formation and especially interesting to experts, and most notably Dr. Jeff Grossman who reviewed and updated its classification upon careful study. By another measure, the common ordinary chondrite, L5, Canadian witnessed fall, VILNA, is one of those very few special meteorites that was imaged during atmospheric entry and a precise orbit was determined. It was not too far from Buzzard Coulee, and what makes it even more special is that it was classified from a (although witnesses heard pieces whizzing around) 94 milligram fragment with fusion crust. The only other specimen found was a 48 milligram piece! This
[meteorite-list] AD: Special: Tribute to Vesta - Four different new and excellent Eucrites!
Dear Collectors, our autumn season we will start with a truly mighty Special. These weeks and months we can say, that we all are captivated by the incredibly fascinating and sometimes almost shocking pictures the Dawn probe transmits through the outer space on our screens from this New World called Vesta. And with each new sight and capture for us meteorite lovers the eagerness grows more unendurable, when finally the first mineralogical data will arrive - and whether then we meteorite collectors could say to the hare: we are the hedgehogs; We were already there. So as a tribute to Dawn and a salute to Vesta we will reveal four different new eucrites all at once, each of them of such a discrete excellence and also of a quality, that we can imagine, that it won't be that easy to make a decision, which specimen to pick, from the kaleidoscope, we try to demonstrate with the diversity of the Eucrite group. Let us begin: NWA 6970 With a tiny tkw of 15.5g only the smallest. A moderately shocked polymict one, which exhibits an extremely busy small scale tessellate. A very dense and compact material, polishing excellently. Internally fresh, with fine spots of colourful inclusions. http://www.chladnis-heirs.com/specials/special-nwa6970.html NWA 6971 Displays gorgeous cubistic shock patterns! Straight and extremely angular shock lines, triangular shock veins and whole slightly shock darkened polygons - and that all in a perfect contrast to an almost Dho 007 looking eucritic matrix. Glossy black fusion crust preserved. http://www.chladnis-heirs.com/specials/special-nwa6971.html NWA 6972 Disguises as a lunaite. As you can see it plays a mimicry of a fine fragmental anorthosic breccia. (And among these NWA 6972 chose the prettiest ones). A high diversity of clasts and inclusions; Highly shocked and Stefan applied a wonderful polishing. Note the black and granular fusion crust on the endpieces! http://www.chladnis-heirs.com/specials/special-nwa6972.html NWA 6974 Elitist extravagance. The climax of our special. A stone like we like it, cause it makes any words obsolete. The Covergirl for any glossy magazine about meteorites or about Vesta. A low shock allowed these different lithologies to merge together to that masterpiece. Overwhelming variety of inclusions. Some weird, some black like coal. Holding our breath now, we only still mention, that it wears a fresh black skin of fusion crust all around (and while we are writing, we recognize, that the price we chose is maybe a little bit too shy). http://www.chladnis-heirs.com/specials/special-nwa6974.html Enjoy the Art of Vesta!

[meteorite-list] AD: Special: The new, fresh and very peculiar Martian meteorite NWA 6963
Dear collectors, Today we have once again the especial pleasure to continue our serial of new finds of unpaired and extraordinary Martian meteorites. It's about the most recent Martian recovery of this year, which has found its way already as NWA 6963 into the Meteoritical Bulletin. Again it is an unusually fresh material. NWA 6963 owns a very good glossy-black fusion crust and the interior presents itself to be absolutely unaltered by terrestrial weathering. What is remarkable about NWA 6963 is that it doesn't belong to the olivine- and olivine-orthopyroxene-phyric main group, but that we have here a basalt, which resembles, if anything, Shergotty. Already the first long- and eagerly awaited cut revealed the fantastic texture of this Mars rock. The crystallization pattern consist of a a dense and angular lattice of broad spindles and bars, much more distinctly and clearer pronounced than that one of Zagami or Shergotty, of which some of you might feel reminded of. And other than these, which are gray, does NWA 6963 attend upon us with an accented greenish tint, which turns that shergottite into an acutely aesthetical delight. Classified was NWA 6963 this time by Dr. Carl Agee at the university of New Mexico. NWA 6963 is highly shocked, so that the plagioclase is completely transformed into maskelynite. The bulk composition is 60% pyroxene, 35% maskelynite, 2% ulvöspinel. Additionally it contains melt pockets with traces of merrillite, pyrrhotite and chlorapatite. Of course no abstracts are on hand yet, according to reports the composition of the pyroxene shall be very similar to that of Shergotty, and hearsay tells, that the bulk chemistry could point also in the direction of NWA 480/1460. Therefore a lot of research is still to do and with that NWA 6963 the scientist certainly will be occupied for quite a while, like it was with the previous, each for its own very special Martian meteorites, where we had the possibility to introduce them here on the list, and so we can look forward to thrilling results and publications still to come! Here you are now. All specimens down to 1.6g do have minimum one fully fusion-crusted edge. The smaller ones sometimes and here and there a few specks of crust. Note also, that this time, seen the news value, the freshness and the specialty of that amazing material among the other Martians and regarding the overall price level of the Martians of the last 2 years, we kept the offer tempting: http://www.chladnis-heirs.com/specials/special-nwa6369.html Enjoy and Success!

Dear collectors, because some of you asked, only that short additional information, also because it isn't so well visible in the photos: That is the approx. fusion crust share of the still available smaller specimens, in % of the circumference: 0.508g 5% 0.603g 10-15% 0.653g 15-20% 0.731g 30% 0.978g 45% 1.018g 40% Find them here: http://www.chladnis-heirs.com/specials/special-nwa6369-2.html All the Best!

[meteorite-list] AD: Special: NWA 6659 prov. - Superior Lodranite
Dear meteorite friends, in our weekly Special we're able this time to present you a wonderful dainty: NWA 6659 - a Lodranite! Lodranites are counted among the absolutely rarest classes a meteorite collector can have in his cabinet and a meteoricist in his lab. Currently the Meteorite Bulletin Database accounts for only 32 lodranitic numbers with a combined weight of 9.39kg (15 of them with 1.14kg yielded the Antarctic campaigns of the last 35 years). And 9 numbers not otherwise specified as belonging to the acapulcoite-lodranite family with 0.33kg (7 Antarctics) - making the lodranites to a much rarer type than any lunar meteorite. Let us say as long-time established meteorite offerers, that it was the NWA-complex of the recent decade, which brought the lodranites at all in the range of the collector and a certain variety of finds into the research institutes. A check of our global price compilation of the season ten years ago only (660 different meteorites, 92 offerers - currently available in the German meteorite forum), gives, that the only chance to get a lodranite was then to acquire micromounts of Lodran, priced at an average of 38,400$ a gram and that among the related acapulcoites, the collector had only the choice between Acapulco (average 1408$/g) and Monument Draw (1016$/g). Lodranites and acapulcoites share common ground and are generic relatives from the same parent body, which seems to have had consisted of a CM or CI-like precursor material. The main differences between these types is the lack of plagioclase in the lodranites and the larger grain-sizes than the acapulcoites display, hence indicating that lodranites underwent during their melt phase higher temperatures and a different cooling period, stemming from deeper layers than the acapulcoites. However, as enigmatic that group perhaps still might be - it are just the very recent years with these new desert finds, which lead science to develop a better understanding of the composition and the complex thermal history of the acapulcoite-lodranite parent body. A perfect overview of the brand-new models and hypotheses you will find on David Weir's meteorite studies pages. The perhaps a little provocative title of this Special we chose, because most lodranitic specimens in our collections are recruited from the large pairing group, which was revised from ACAP to LOD and where we once all tried to put the numbers together here on the list (NWA 2565/2714/2866 seqq.) And we regard NWA 6659 as definitely more comely. It is better preserved than the old group, which had weathering grades of W3 and W3-4. Not only the crystals of NWA 6659 are still relatively fresh-looking - it has even here and there some metal grains and of course: Yes - the so highly desired Triple Junctions superabound. All slices were grinded and polished successively with 6 different grits; and you find them here: http://www.chladnis-heirs.com/specials/special-nwa6659.html Regarding the statistics from above, keeping in mind, that the Great Desert Area is coming to an end and emphasizing that we price NWA 6659 at the lowest edge of the lodranite spectrum, we think, that these specimens are not only of highest interest for the advanced collector, but would wholeheartedly commend them as an excellent choice also for the beginning meteorite enthusiast, as one-and-only specimen for having an perfect representative, once and for all, of that fascinating and so exceedingly rare class.

[meteorite-list] AD: ALL slices do have METAL Flakes - of the Superior Lodranite NWA 6659
Hello again, And sorry for the little explanation, but for not all jumping on the 5.013g and the 4.397g-slices, respectively being disappointed, that those are gone: ALL slices do have the same amount of metal flakes and blebs! It's only not so well visible, as we photographed only two with an angle of the light, that the metal flakes are reflecting. All slices are the same wonderful! http://www.chladnis-heirs.com/specials/special-nwa6659.html And when we are just at addendums... The unpaired new fresh Martian with that fantastic texture, where we perhaps made the mistake to introduce it with too soberly chosen attributes last week. NWA 6963. There we would invite those, who'd still need a smaller sample than those slices currently left, to inform us, which weight they prefer - for us to pre-plan, what and how we still have to cut or to divide into smaller sections. http://www.chladnis-heirs.com/specials/special-nwa6369-2.html and http://www.chladnis-heirs.com/specials/special-nwa6369.html Many thanks in advance!

[meteorite-list] AD: Special: Extremely aesthetical new H-Metachondrite NWA 7024 - and an Eucritic Surprise NWA 6969
Dear meteorite friends, Stefan has prepared for this weekend Special again two enchanting gems. NWA 7024 is a new H-metachondrite. About metachondrites, in connection with type-7, PACs and even melts, we spoke detailed and it was discussed on the list, that this concept offers a higher taxonomic clarity, when we introduced the first L-metachondrite one year ago. Therefore you find it in the list-archives and we haven't to recur. (And in case, David Weir will be as helpful as always: http://www.meteoritestudies.com/ ) NWA 7024 is now a rock, that underwent a metamorphosis to such a degree, that none of the chondrules of the precursor material prevailed and that a complete recrystallization took place. Well, and this time, especially if we compare it to the very few known H-metachondrites, let us demonstrate additionally a completely non-scientific attitude: It is a beautiful meteorite! Internally very fresh, the photos hardly can do justice to the aesthetics of the specimens. Just note only the shape and the distribution of the iron-flakes - doesn't it resemble Itqiy, does it? And Stefan has applied an especially fine finish to the surfaces; so that all in all, we really don't have to accentuate the rareness of the material or the importance for the systematics of your collection. It is simply again a case for the high-end collector, two whom not size matters but the unwontedness and the classiness of a meteorite - a case for his casket of remarkable space jewels. http://www.chladnis-heirs.com/specials/special-nwa7024.html As we chose a moderate price and because the number of specimens is so limited by the small tkw, that unavoidably some collectors will miss out, let us add a second fantastic meteorite: NWA 6969, a wonderful little eucrite! Here already the specimens: http://www.chladnis-heirs.com/specials/special-nwa6969.html That marble came as a complete, fully freshly crusted stone. As you can see on the backsides of the endcuts best, that fusion crust was so atypical, that for the experienced specialist this little marble was definitely too tempting to let it pass by! Cut it revealed to be a monomict eucrite with a gorgeous brecciation and shock vein pattern. The basalt is looking not that common too - so imagine, what for tricks you can play e.g. with the 0.584g or the 0.494g in showing it to the meteorite connoisseur, when he visits you, in asking him for his expert opinion.

[meteorite-list] AD: Special: NWA 6966 prov. - a Classy and Elegant new Eucrite
Dear Meteorite Friends Fittingly to the season we'll introduce today to you a very fine new eucrite: NWA 6966 prov. Some of you might remember the number, as the stone before cutting was displayed due to its aesthetics already in Paul's MPOD before: http://www.tucsonmeteorites.com/mpodPic.asp?DD=10/28/2011WYD= NWA 6966 came as strongly flight oriented stone of 1105 grams, unfortunately with a not fully complete fusion crust, but with some areas missing - else it would have been a remarkable and true museum's specimen. Nevertheless it was of a fine fresh appearance and the fusion crust exhibited radial flow lines. So the slicing was well worth, as the outcome resulted in, in our opinion, very desirable specimens of attractive dimensions. NWA 6966 presents itself as a weakly shocked polymict eucrite. Most striking to the eye are the basaltic, typically freckled large eucrite-nests, emerging from the especially fine grained matrix. Other than the wilder polymict ones, the inventory of the clasts is more limited and the colors and tints more monochrome, .bestowing upon that material an especially elegant and wintery noblesse. Here you find now the fine-grinded, fusion crusted and moderately priced slices: http://www.chladnis-heirs.com/specials/special-nwa6966.html Greetings out of the first snow, Martin Stefan Chladni's Heirs Munich - Berlin Fine Meteorites for Science Collectors http://www.chladnis-heirs.com __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Dear list-members, let us contribute to the discussion about that new Martian fall, which certainly belongs to one of the most exciting events in all our collector-lives, in sharing some pictures of a stone, which is the most amazing example of this new fall, we have seen so far. The specimen is a completely fusion crusted individual with a weight of 147 grams. The pristine and extremely clean crust displays a fantastic deep-black gloss. Furthermore it shows indications of a slight orientation, if you note the lipping running over the edge to the left. http://www.chladnis-heirs.com/new-meteorites/tissint.html Simply enjoy!

[meteorite-list] Special: AD: New Mars-Fall Tissint - Polished Fullslices!
Dear community, Now we all were occupied with admiring the fragments and the rare individuals that new epoch-making fall yielded; we studied the exterior, were amazed about the variety of different fusion crusts, took a glance on the interior by means of broken sides or crust-free fragments. Now it is highest time to subject Tissint to the other viewing habits we are used to - and here we are proud to present now the first masterly prepared slices: And what for slices! http://www.chladnis-heirs.com/specials/tissint.html In principle here could end our Special - in leaving you alone in your awe. Well worth it was, that we pushed away our twinge of conscience to slice up one of the scarce perfect individuals, any collector would rip his arm off for. Look, how we were rewarded. See those fantastically pastel green olivine crystals, which strongly remind us of those in NWA 5789. Take a closer look, you'll find even a few single ones, which seems almost to change from opaque to translucent. They are sitting in a very accentuated matrix-grid, which is in some ways similar to Shergotty or Zagami, though finer and on a smaller scale. And finally those dramatic and huge melt pockets and maskelynite blotches. With all historical respect for the four other observed Martian falls, Tissint is macroscopically the most spectacular and the most aesthetical among the observed falls. For sure. Masterly polished by Stefan's craftsmanship, completely surrounded by fusion crust, with at best only here and there naturally a small chip missing, are these those adorable specimens, which also in later decades you'll take in your hands, with a silent and almost triumphal blitheness, to have been once so wise, to have saved these specimen just in the days of the birth of this so famous meteorite. And if you were one of the few lucky ones, who were able to gather one of the few complete individuals, such a fullslice is almost a must to add. (And those who weren't - watch the endcut, a perfect alternative or contact us for still a superb complete individual). Enjoy!

[meteorite-list] AD: Special: An unique and truly exotic anomalous Mesosiderite - NWA 7025
Dear List community, as it wouldn't be already a really rare event, that a new unpaired mesosiderite can be introduced, we have today a by all means astounding stone, worthy for one of our Specials: NWA 7025. Well... if you take a look on the cut surfaces, we think, you'll tend to guess or to reckon, to have here an evolved achondrite. Those chrystals, no metal visible. Nevertheless not looking too weathered - Maybe a brachinite... To shorten it, we leave the word to the expert. Here is the gobsmacking report of the classification: The specimen contains two distinct domains in contact along curvilinear boundaries. One lithology consists predominantly of orthopyroxene with subordinate anorthite, ~25 vol.% troilite+metal (kamacite and taenite as small cuspate grains), accessory chromite and merrillite, and appears to be a variety of mesosiderite. Other portions of the specimen have similar mineralogy, except that most of the troilite and metal has been replaced by small cuspate voids (with the same general shape as the troilite and metal grains in the other lithology), and there is a narrow transitional zone between these domains (see image below). The overall mineralogy and the orthopyroxene compositions (Fs26.3-26.5Wo2.9-3.1, FeO/MnO = 26-28) are typical for mesosiderites, and oxygen isotopic compositions determined on acid-washed subsamples by laser fluorination at Okayama University (d17O 1.961, 1.847, 2.082; d18O 4.149, 3.992, 4.387; D17O -0.223, -0.255, -0.228 per mil) also are consistent. This specimen appears to be a mesosiderite, which has undergone terrestrial weathering by infiltration of fluids that selectively leached much of the primary troilite and metal in some parts of this meteorite. It is an anomalous, an altered mesodiderite! Our baffling and surprising NWA 7025. A stone for the expert. A stone for the collector aiming for the really all new. And now we invite you to order your specimen, as always prepared to the standard, you're used to from Chladnis Heir's, and as long as that surprise lasts: http://www.chladnis-heirs.com/specials/special-nwa7025.html Success!

Re: [meteorite-list] What is Chladni's book on 18 meteorite falls title?????? (Stuetz)
Hi Shawn, the paper by Andreas Xaver Stuetz, you're looking for, was published in Born's Trebra's Bergbaukunde, second volume, 1790. You have it here online: http://kuerzer.de/shawnstuetz Page 398 - 409. In fact he reports there from the fall of Eichstädt, mentions the Pallas-Iron and gives at length a report about the fall of Hraschina - with eyewitness observations, in translating the report about the fall by Wolfgang Kukulyewich, vicar of Agram. Here and there he gives some ironic remarks. Stuetz is classifying these reports as fairy tales, closing the article with a lengthy explanation, that these stonesirons were formed by lightning. Best!

Re: [meteorite-list] Pairing discussion/questions
Hello Jeff, This statement, appearing in some of the recent emails, is wrong. Really? I was speaking about different meteorites. M.Lindstrom R.Score came to the the result, that the average number of Antarctic meteorites per pairing group is 5. M.Lindstrom, R.Score: Populations, Paring and Rare Meteorites in the U.S. Antarctic Meteorite Collection http://www-curator.jsc.nasa.gov/antmet/ppr.cfm And where in the world did this figure of billions of dollars being spent by the US to collect its 20,000 meteorites come from? Not the U.S. - USA, Japan, China, Europe together. Antarctic is an expensive place to work and to live. You need special equipment, you have to transport everything there, you have to maintain the infrastructure, and like with any other program, you have the running costs for the personnel (salaries, social insurances, working place costs). The figures are scattered over the web. There you can read, only to give some examples, that one standard ANSMET team causes 800,000$ primary costs without secondary costs for 6 weeks on the ice - and that the whole Antarctic summer semester over would be hunted. Somewhere you will find, that the supply and the transport of fuels to maintain the McMurdo Station costed 70 millions $ in one year. And so on. Personnel costs too, remember EUROMET, who had basic costs for personnel without any expedition yet of 20 millions $ per year (they went also to Antarctica). Labs, tertiary costs - it will be all difficult to amount. (Would be interesting, if someone would do this once). Well and then think, that not only the U.S. are hunting there, but for a similar long time NIPR, then the few EUROMET trips, as well as China. Well and that for 33 years... will easily sum up to a total of far more than a billion. Personnel, equipment, insurances, pension plan, fuels, transportation, administration, These costs the public hasn't to pay, if they are buying NWAs. The Bulletins you know. Seen the tkws and the numbers from almost all rarest, rare and semi-rare types - it was meanwhile more found in NWA than in Antarctica. An unclassified averagely weathered kg NWA-OC delivered to your doorstep costs you around 30$. What does it cost to recover 1kg of an averagely weathered OC in Antarctica? How long does it take and what did it cost to find 19 different lunaites in Antarctica for USA, Japan, Europe and China together? 33 years. How long takes the same task in the private desert sector? 5 years. What does cost 1 1/4 kg of an classified R-Chondrite from NWA? 12,000$? In 33 years of Antarctic expeditions in total R-chondrites were found: 1 1/4kg. A scientist is accepted to take part in an ANSMET-hunt. He steps out of the door in sunny Arizona - will 12,000$ be enough to reach his final destination? Jeff, don't get me wrong please. It is not my intention to play the cold desert hunts off against the hot desert hunts. The Antarctic meteorite programs are wonderful, great, absolutely necessary and the expenses more than justified. But in my opinion it would also extremely stupid, if science would abstain from the NWA and Oman finds, and wouldn't work additionally on them. Because they are meanwhile even more manifold than the Antarctic finds, outweigh them by mass, and cost the public compared to the Antarctic finds virtually almost nothing at all. To set them aside would IMHO also not directly justifiable to the public, because, sorry to say that, but sometimes it is forgotten, ANSMET, NIPR, PRIC, ect. are paid with public tax-money. I'd say, Martin -Ursprüngliche Nachricht- Von: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com] Im Auftrag von Jeff Grossman Gesendet: Dienstag, 19.

How many different meteorites do we have from Antarctica after a third of a century hunting and spending billions of USD? 7000. This statement, appearing in some of the recent emails, is wrong. There are over 16,000 classified meteorites from the ANSMET expeditions, plus a few thousand unclassified. Counting the Japanese, Chinese,European, Korean, and minor collections, There ~27,000 classified Antarctic meteorites, and probably close to 20,000 not yet classified (mostly in the Japanese and Chinese collections). And where in the world did this figure of billions of dollars being spent by the US to collect its 20,000 meteorites come from? Also, don't overlook the fact that Antarctic meteorite have proven to be vastly more valuable scientifically than NWA meteorites. They probably occur as subjects of scientific publications at 10x the frequency as NWA meteorites (I posted statistics on this some years ago, but can't locate it at the moment).

Re: [meteorite-list] Dumb Questions About Meteors Meteorites
Hi Erik, unfortunatly most of these balls are also anthropogenic pollution. Especially industries like coal-burning power plants, foundries and metal processing produces such spherical particles. That's why one has either to go in the stratosphere to collect micrometeorites or to use unpolluted sources like Antarctic wells or ice or sediments - from the times where there wasn't human pollution, to be able to isolate them. Especially in the late 70ies and early 80ies it was quite a fashion among the collectors to try to find micrometeorites by filtering rainwater. Best!

Pick up magnetic material in tray with your magnet and set on paper to dry. Observe material with a good- strong microscope. Some of what you see will be spherical balls- those are the micrometeorites. Steve from the nuggetshooter forum(http://www.nuggetshooter.ipbhost.com/index.php?showforum=4) posted that 2 years ago.

[meteorite-list] AD: Special - Fabulous New Diogenite - NWA 6024 prov.
Dear collectors, Today we have the pleasure to present you an in our eyes - simply wonderful stone: NWA 6024 - a new diogenite. We all are aware of the Vesta-debris-breccias, where the bow is drawn from the polymict eucrites with their often typically light-grey matrix - over the howardites - to the polymict diogenites. And at the diogenitic end we arrived with NWA 6024. And to what an end we came! NWA 6024 is by all means unusual, as it contains these large smashed blackish pyroxene crystals, giving it an extraordinary appearance. This diogenite is looking so characteristically, that we are not aware of any other similar NWA at present so that we strongly presume that it is probably unpaired and a really new one. Never before it was so easy for us to advertise a diogenite. Just watch the pictures and youll know why! Here the data: NWA 6024 prov. Morocco 2009 Tkw 65g Diogenite Shock stage: moderate, Weathering grade: low Unfortunately it had a low weight. Fullslices we priced at 45$ a gram, 40$ a gram for the endcut with patches of remaining fusion crust. And here you are: http://www.chladnis-heirs.com/special-nwa6024.html Enjoy!

[meteorite-list] Quick-AD: Last SMALL Specimen of very special Martian NWA 5990 Last New Halfa
Good afternoon, today we want to give only a short note on 2 specimens. First is a sample of the most noteworthy new Martian NWA 5990. Here again the abstract, outlining its special rank among the Martians: http://www.lpi.usra.edu/meetings/lpsc2010/pdf/1833.pdf There, because several collectors were somewhat worried not being able to add this important Martian to their systematics, because originally only full- and half-slices were available, we sacrificed a half-slice to make smaller samples for them. These are all distributed now, but we have a surplus sample left. A quarter-gram (0.256g) partslice. Unfortunately this specimen is already the last opportunity for the private collector, still to add such a smaller sample of this Martian to his collection. Secondly: We forgot to piggyback on Martin Horejsi's fine article about New Halfa in the November issue of the Meteorite Times. http://www.meteorite-times.com/Back_Links/2009/november/Accretion_Desk.htm There we would have still a partial endcut left, 33.60g, with some fusion crust. Stems from a fragment, somewhat larger than a fist, which we acquired years ago from the eyewitness Mr.Khalil, who is also mentionned in the Bulletin entry. (The Catalogue of Meteorites has a little mistake, the fall happened close to village N°19 and not N°9). Mr.Khalil and friends were going there from door to door, asking the locals, whether they may had collected some pieces, but without success, because then not many dared to leave the house, because all thought that sound phenomena of the fall would origin from a rocket assault. The fall area itself is destroyed by agriculture, so that it's highly unlikely that still finds could be made there. Would maybe also interesting not only for private collectors, if one thinks, that from the top-twenty collections of the World none, but Berlin (8 grams) has this observed fall. Well, instead to incite a longsome bidding battle on ebay for these two last specimens, we'd rather say, just send us an email for pictures and details, if interested. Have all a fine Sunday!

Dear Abdelfattah, this is a really sad and the more shocking news, as we met Mbarek just a few weeks ago and found him in his always jocund and friendly mood. We and we think we can speak also for all the countless collectors, researchers and curators keeping knowingly or unknowingly specimens in their collections from the stones, which had passed through his hands, are grateful to his contribution and will honour his memory. Today the meteorite family has lost a good man. Saddened we express our condolences to Mbarek's family and his friends.

Mbarek is a serious and honest confidant man who helped the science in field of meteorites. the majority of meteorites that have the scientific, collectors and dealers coming from this person. and I think many people know Mbarek or heard about him and specialy those who have visited Morocco. Mbarek is a person well experienced in meteorites. the world of meteorites has really lost a wise man and the active tillering person. I do not know what to say about this person. He has a good and exellent performance. I worked with him for years. ( INA LI ALLAH WA INA ILAYHI RAJIOUNE) we are all to GOD and to GOD we return. Cheers, Abdelfattah. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
