Re: [meteorite-list] Meteorite 20 Questions - Answer and Share if you Dare. :)
1) When did you start collecting? (how long ago) Around 4 or 5 years ago. 2) What first interested you about meteorites? My mom teach me to love astronomy, but I've always looked for something more tangible in it. Once, in a meteor shower, I've realised that meteorites could be a way. Then, I've started to learn about meteorites and that I could collect them. 3) What was your first meteorite purchase, and from whom? Well, there were two first meteorites. My first first meteorite I've bought from a mineral store in a city called Campinas (here in Brazil), but one year later I realise that it was a meteorwrong. My second first meteorite is a Bendego that I've bought from a serious brazilian dealer. 4) How many meteorites or localities do you currently have in your collection? 23 and growing (slowly, but growing, hehe). 5) If you had to know for insurance purposes, what do you value your entire collection at? - in dollars - ballpark figure OK, or just say none of your business. I don't know. I think that I'll never stop to calculate how much they could cost, they are priceless for me. 6) What is your favorite meteorite and why? My favorite meteorite from my collection or from all? In my collection is my Campos Sales - It shows the exact things that I could expect from an stony meteorite, from the crust untill the condrules. From all the meteorites in the world it's the Marília meteorite - It's fallen only 30 km from where I live but it'd happened 18 years before I've been born. Its strewfield is the only one I've ever been in. 7) Have you ever found a meteorite in the field? Unfortunately no... 8) Did you ever get the deal of a lifetime on a meteorite? If so, what was it? No. 9) Did you ever go through the ordeal of a lifetime to obtain a meteorite? If so, please explain. Well, I'm still in a 5 years battle to get at least a small amount of the Marilia from one of the hard-to-deal museums from Brazil. 10) Have you ever consumed meteoritic material? (If so, how or under what circumstances?) Probably. Last month I was trying to open a small window in a uNWA in my home and it made a lot of dust. Probably some fell over some biscuits near me that I ate after end the work, hehe. 11) Does your spouse share your meteorite passion, is ambivalent towards it, or resents it? My girlfriend says the they are nice, but doesn't go beyond this. 12) Have you ever let a bill go unpaid or late to buy a meteorite? No. 13) A perfectly oriented, fully crusted, baseball-sized, lunar meteorite crashes through your roof and lands in your lap while you are reading this. It's the most gorgeous aesthetically-superior specimen you have ever seen - like Lafayette, but better. It legally belongs to you. What do you do with it? Well, first of all, I'd go nuts! After some hours to calm down, I think I'd take some photos and document everything. I'd take the pieces of the roof and of everything touched by the meteorite (less me, of course, hehe) to donate to a museum. I'd cut the meteorite in half and take the front part for me. The other half I'd take to classify and the rest I'd donate to museums and closer friends that collect meteorites (except one slice that I'd swap for a Marilia piece). 14) Statistics have caught up with someone. Anne Hodges will no longer be the only documented person to be struck by a falling meteorite. Assuming the next person struck could be anyone and you could pick that person, who would it be? (silly answers only, nothing mean or political) If it wouldn't wound anyone, I think I'd choose my daddy. He'd finaly look the meteorites with other eyes, hehe. 15) You are awarded the honor of selecting one specimen to keep from any meteorite collection in the world. What would it be? OMG, this is really a hard question... All meteorites that I can think of (even the Marilia) are so incredibly beautiful that, if I could get them, I'd put in a museum again... 16) Have you ever sold or donated your entire collection, and then had to rebuild it? No. 17) Summarize what you think about tektites in one sentence. Interesting material that calls the people attention due its history and that make a nice presence in a meteorite collection. 18) Which do you prefer - thin sections, whole specimens, slices, or endcuts? In order: whole specimens, end cuts, slices and thin sections. 19) Do you collect meteorwrongs? I'm at university by now, I don't have money enought for this and for the meteorites at the same time, hehe. Maybe something for the future... 20) Have you ever dropped a tiny crumb of a rare meteorite and lost it? Fortunately no (yet). Nice questions. I laught a lot thinking to answer them! __ 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
Re: [meteorite-list] Scientist Warns Massive Asteroid CouldHitEarthin 2182
List, Count, Ejecta get sorted by mass -- big chunks near the crater, then medium chunks in the middle distance and so on. At about 300 miles from impact, there is still a noticeable dustfall from an impact this size. And the smallest particles get blown into the atmosphere world-wide as micron-sized dust. The statistical average speed for ejecta is always less than the impact velocity because a lot of energy is used up in the fireball, vaporizing the impactor, vaporizing a roughly equal mass of target (Earth!), melting target rocks, and lastly, fracturing target rocks to be ejected. The chances of a piece of ejecta getting kicked up to even sub-orbital velocity is small, but with this many pieces in play, it MIGHT happen to a very small number of pieces. So, no large quantities of ejecta would behave as you asked. The only real-world example of high speed ejecta is tektites, which seem to be vaporized target rock that condenses into liquid and cools to a plastic glass very quickly, probably above the atmosphere. They can travel up to half an Earth diameter. But that's the only example we have to go by, and it's mysterious -- why doesn't every impact produce tektites? But for 99.9% of ejecta, it's the same old story everywhere on every planet. Google up pictures of ejecta blanket. http://www.google.com/images?hl=enq=ejecta%20blanketum=1ie=UTF-8source=ogsa=Ntab=wibiw=967bih=640 Big, blocky chunks just outside the rim, tapering off to dust at the edges. That's the interesting thing about kinetic events -- they're all the same. Once you get up to a good size, the particular characteristics don't matter much. In this size of event, an equal weight of impacting ice, or rock, or iron, or feathers, or rocky road ice cream -- they would all leave an almost identical crater. All that counts is the total kinetic energy. Objects get blasted off planets. Mars meteorites somehow got off Mars. Lunar meteorites somehow got off the Moon. There are even folks who think a chunk of Mercury could somehow get off Mercury (which chunk is the question). Moreover, they seem to sometimes do it without being shocked, possibly by being sucked up the tube of vacuum formed when the impactor blows through the atmosphere. No one knows how exactly, but it happens, I suspect, as a rare event. Not to be callous, but an eight-mile crater is a medium impact, with local effects, not regional effects, not continental effects, not world-threatening effects. But like any explosion, it is nastier the closer you happen to be to it. It could take out about half of the state of Iowa, for example. Beyond Iowa's borders, damage would be minimal. Still, Iowa...

Re: [meteorite-list] Gebel Kamil webpage
I had this post as a draft earlier - seems a perfect time to post it: Hello All, The initial expedition did in fact find more than one *complete individual* from the fall. If you take a look at the following website, you'll see links to two photos: http://www.b14643.de/Sahara/Kamil_Patatrac_Crater/index.htm Photo links: http://www.b14643.de/Sahara/Kamil_Patatrac_Crater/Kamil_1big.jpg http://www.b14643.de/Sahara/Kamil_Patatrac_Crater/Kamil_3big.jpg Take a look at the first and second photos. Those are both in-situ photos; the meteorites have yet to be moved, or the dirt around them disturbed. Also note the differing shapes and the surface patina of each iron. I initially thought that the iron might simply have been rolled over - but take a look at the patina visible in each photo. The surface of Gebel Kamil irons varies greatly: especially the contrast between exhumed and buried surfaces. Exposed surfaces typically exhibit a dark patina and sometimes corrosion pitting. Buried surfaces are often better-preserved, but look entirely different; they're rusty. Both of the photos above are of the upper, sandblasted surfaces of meteorites that have yet to be moved from where they were found. So, two or more individuals.

Re: [meteorite-list] Gebel Kamil webpage
The effects of sand abrasion (corrasion) and chemical weathering (corrosion) of objects on a desert surface, apart from other factors, depend considerably on the texture and composition of the original surface, but also on the dimensions and the depth to which an object is buried in the soil. It does make a difference whether the surface to be attacked is coated by a smooth layer of magnetite and other iron oxides (fusion crust), or whether the surface is a shear surface without any protective coating (and with large micro surfaces inviting contaminants to adhere). Also the forming of caliche or calcrete due to evaporation and condensation processes in hyper arid regions is usually limited to a very narrow zone close to the surface. Parts of objects buried beyond this zone or protruding above it, are affected in a much lesser degree. This effect can be observed quite well on Kamil shrapnel. These conditions allow to interpret caliche deposits on desert meteorites in certain cases as markers, indicating previous ground levels of deflation zones. The strongest activity of chemical weathering in hyper arid environments is limited to this very zone as well. If we look at the majority of the corrasion activity, which is one of the factors responsible for the characteristic sub-milimeter pitting on the Kamil-shrapnel, it is limited to a specific zone as well. At normal prevailing wind velocities the leaping motion of quartz sand grains (called saltation), which abrades the surface of an obstacle, is usually limited to 0 – 5 centimeters above the ground. But most of the damage occurs in the lower region of the saltation zone. Thus, conclusions drawn from weathering patterns of iron objects of different sizes, surface qualities and burying levels should be considered with caution.

Re: [meteorite-list] Meteorite 20 Questions - Answer and Share if youDare. :)
Greetings, This looks fun so here are my answers. --AL Mitterling 1) When did you start collecting? (how long ago) Officially 1986/7 but first purchase of meteoritic material was in 1966 2) What first interested you about meteorites? Going to Meteor(ite) Crater in the 1960's and seeing their display as well as going to the Field Museum in Chicago and looking at specimens. 3) What was your first meteorite purchase, and from whom? Canyon Diablo from Meteor(ite) Crater 4) How many meteorites or localities do you currently have in your collection? Well over 350 unique locations. 5) If you had to know for insurance purposes, what do you value your entire collection at? - in dollars - ballpark figure OK, or just say none of your business. Can't comment on this. 6) What is your favorite meteorite and why? I have many but one is a 7 gram full lunar slice. Growing up during the Apollo era and seeing a lunar specimen brought back from the Moon, I always hoping that some would come on the market and with the Lunar Meteorite finds that dream came true and I have a number of nice Lunar Specimens now. 7) Have you ever found a meteorite in the field? Several but no cold finds. I have hunted Holbrook with some success, Odessa and Park Forest. 8) Did you ever get the deal of a lifetime on a meteorite? If so, what was it? I've purchase a number of great lifetime specimens. One was a Camel Donga 600 gram whole. 9) Did you ever go through the ordeal of a lifetime to obtain a meteorite? If so, please explain. Yes, but that is just dealing. Many of my Indiana specimens are just that, including a full slice of Noblesville, Indiana a 20 gram, one if not the only one of the full slices left. Same with my Lafayette, Indiana Martian Specimen. 10) Have you ever consumed meteoritic material? (If so, how or under what circumstances?) No, I think that is sort of silly, I have rescued some from that fate and have sold them. Probably everyone eats microscopic material that settles down on crops or gardens. 11) Does your spouse share your meteorite passion, is ambivalent towards it, or resents it? She is reasonably interested in my collection pieces and often hangs around when I am finishing specimens for others or myself that don't look good and then likes to see the transformation after I am finished. She see my yearly sales so doesn't complain. A few purchases have made her eyebrows rise a little, especially the 5 figure ones. 12) Have you ever let a bill go unpaid or late to buy a meteorite? Delayed payment but only a week or 10 days. 13) A perfectly oriented, fully crusted, baseball-sized, lunar meteorite crashes through your roof and lands in your lap while you are reading this. It's the most gorgeous aesthetically-superior specimen you have ever seen - like Lafayette, but better. It legally belongs to you. What do you do with it? Keep it of course but share it with others. (I saw someone else say they would cut it in half that is meteorite sac-religious!!!) I would permit a core to be taken and studied for classification. I'd send it to Alan Rubin! Waitthere is some noise.ouch!!!#$%%@ a lunar just crashed through my roof If you believe that I've got a bridge I'll sell you. 14) Statistics have caught up with someone. Anne Hodges will no longer be the only documented person to be struck by a falling meteorite. Assuming the next person struck could be anyone and you could pick that person, who would it be? (silly answers only, nothing mean or political) The Mbale fall struck a boy in the strewn field (see Sky and Telescope) Hummm.anyonethere is a few people on the...never mind. 15) You are awarded the honor of selecting one specimen to keep from any meteorite collection in the world. What would it be? That's a hard one to answer but I think the Springwater that Nininger found from ASU would be my first choice but I have many. 16) Have you ever sold or donated your entire collection, and then had to rebuild it? No, but I donate specimens to various places and people like teachers. I have brokered collections that collectors wanted to go to a museum. 17) Summarize what you think about tektites in one sentence. Mysterious interesting differentiated glassy objects that are probably a result of terrestrial impact. 18) Which do you prefer - thin sections, whole specimens, slices, or end cuts? By thin sections are you referring to slides?? I collect whole specimens, slices of same and if possible a thin section slide of same. (thank you Bernd for getting me started. :-) 19) Do you collect meteor wrongs? Yes, since I have many people send in items to me all the time, the ones I don't send back or throw out on the big pile out back, I keep to show people what various meteor wrongs look like. 20) Have you ever dropped a tiny crumb of a rare meteorite and lost it?
Re: [meteorite-list] Gebel Kamil webpage
Hello Svend, All, I probably have as much experience as you do with desert irons; I agree, but look at the photos. The first shows an xxkg half-buried individual (the 83 kg?) that clearly protrudes more than 5cm above the ground. Furthermore, you can tell very clearly that it is well-embedded in the ground. The second photo shows a meteorite that exhibits obviously different features. But both irons are right-side-up. Compare to other Gebel Kamil irons that have been found. They all show painfully clear differences in colour and texture: http://shop.ebay.com/?_from=R40_trksid=p3984.m570.l1313_nkw=gebel_sacat=See-All-Categories - Or are you telling me that you can't tell which side was facing down in all of those photos? ...And both are sitting in undisturbed soil. It takes one hell of a strong guy to pick an 83 kg iron up and toss/drop it so that it lands without disturbing the dirt around it. In fact, if you look at the soil in each photo, it is *completely* undisturbed. Neither one of those irons was moved before the photos were taken.

I initially thought that the iron might simply have been rolled over - but take a look at the patina visible in each photo. The surface of Gebel Kamil irons varies greatly: especially the contrast between exhumed and buried surfaces. Exposed surfaces typically exhibit a dark patina and sometimes corrosion pitting. Buried surfaces are often better-preserved, but look entirely different; they're rusty. Both of the photos above are of the upper, sandblasted surfaces of meteorites that have yet to be moved from where they were found. So, two or more individuals.

At about 300 miles from impact, there is still a noticeable dustfall from an impact this size. And the smallest particles get blown into the atmosphere world-wide as micron-sized dust. The statistical average speed for ejecta is always less than the impact velocity because a lot of energy is used up in the fireball, vaporizing the impactor, vaporizing a roughly equal mass of target (Earth!), melting target rocks, and lastly, fracturing target rocks to be ejected. The chances of a piece of ejecta getting kicked up to even sub-orbital velocity is small, but with this many pieces in play, it MIGHT happen to a very small number of pieces. So, no large quantities of ejecta would behave as you asked. The only real-world example of high speed ejecta is tektites, which seem to be vaporized target rock that condenses into liquid and cools to a plastic glass very quickly, probably above the atmosphere. They can travel up to half an Earth diameter. But that's the only example we have to go by, and it's mysterious -- why doesn't every impact produce tektites? But for 99.9% of ejecta, it's the same old story everywhere on every planet. Google up pictures of ejecta blanket. http://www.google.com/images?hl=enq=ejecta%20blanketum=1ie=UTF-8source=ogsa=Ntab=wibiw=967bih=640 Big, blocky chunks just outside the rim, tapering off to dust at the edges. That's the interesting thing about kinetic events -- they're all the same. Once you get up to a good size, the particular characteristics don't matter much. In this size of event, an equal weight of impacting ice, or rock, or iron, or feathers, or rocky road ice cream -- they would all leave an almost identical crater. All that counts is the total kinetic energy. Objects get blasted off planets. Mars meteorites somehow got off Mars. Lunar meteorites somehow got off the Moon. There are even folks who think a chunk of Mercury could somehow get off Mercury (which chunk is the question). Moreover, they seem to sometimes do it without being shocked, possibly by being sucked up the tube of vacuum formed when the impactor blows through the atmosphere. No one knows how exactly, but it happens, I suspect, as a rare event. Not to be callous, but an eight-mile crater is a medium impact, with local effects, not regional effects, not continental effects, not world-threatening effects. But like any explosion, it is nastier the closer you happen to be to it. It could take out about half of the state of Iowa, for example. Beyond Iowa's borders, damage would be minimal. Still, Iowa...

I happily acknowledge your experience Jason, but that is not the point. I can only speak for myself, and I do not base such statement on a photo without any chance to study the evidence in situ. By the way, the original source of both pictures you quote is the Museo Nazionale Antartide, although the source you quote does not give credits and has obviously changed the aspect ratio of the second photo to make it fit the website template. In the supplement to the Science-express article of Folco et al. on the Kamil crater, the left photo has the original caption: An 83 kg meteorite specimen found 230 m due north of the crater showing regmaglypts The photo on the right, which is from the Museo Nazionale Antartide Kamil crater website, has the original caption: largest recoveredmass ca. 80 kg. Luigo Folco from the Museo Nazionale, the head of the Kamil expedition, wrote in the express version of his article in Science, that the finds of his team consisted of shrapnel except one individual fragment of 83 kg”. I see no reason to doubt his words. Regards, Svend Jason Utas meteorite...@gmail.com hat am 29.

It takes one hell of a strong guy to pick an 83 kg iron up and toss/drop it so that it lands without disturbing the dirt around it.

It does make a difference whether the surface to be attacked is coated by a smooth layer of magnetite and other iron oxides (fusion crust), or whether the surface is a shear surface without any protective coating (and with large micro surfaces inviting contaminants to adhere). Also the forming of caliche or calcrete due to evaporation and condensation processes in hyper arid regions is usually limited to a very narrow zone close to the surface. Parts of objects buried beyond this zone or protruding above it, are affected in a much lesser degree. This effect can be observed quite well on Kamil shrapnel. These conditions allow to interpret caliche deposits on desert meteorites in certain cases as markers, indicating previous ground levels of deflation zones. The strongest activity of chemical weathering in hyper arid environments is limited to this very zone as well. If we look at the majority of the corrasion activity, which is one of the factors responsible for the characteristic sub-milimeter pitting on the Kamil-shrapnel, it is limited to a specific zone as well. At normal prevailing wind velocities the leaping motion of quartz sand grains (called saltation), which abrades the surface of an obstacle, is usually limited to 0 – 5 centimeters above the ground. But most of the damage occurs in the lower region of the saltation zone. Thus, conclusions drawn from weathering patterns of iron objects of different sizes, surface qualities and burying levels should be considered with caution.

Re: [meteorite-list] Gebel Kamil webpage
Hello Bernd, Svend, All, 1) The background for each photo is significantly different. One is loose sand. The other, large rocks. The photos were therefor not taken in the same place. 2) The photo on the left is pretty clearly the iron before it was moved. It's well-embedded in undisturbed ground. The photo on the right...maybe not. We can't tell if that iron is sitting on the ground (so it could have been moved there). 3) If we're to assume the photo of the iron on the right is of the same iron, we have to wonder about why they would have removed it from its hole (on the left), moved it to a rocky area (photo on right), put some soil on top if it (note that it's clean on the left), and then took another picture of it, with a GPS next to it, as though they're recording a find location. Of course, the GPS could just be for scale, but since they didn't use a GPS for scale purposes with the left hand (clearly in-situ) photo, it seems unlikely that they would then use it exclusively for scale purposes after moving the iron. -All the less likely because the first photo shows a fairly wide angle - and there are *no* rocks nearby. I suppose you could count this as circumstantial evidence, because the iron could have been exhumed, moved, covered in dirt, and then photographed, but this seems very unlikely. Regardless, the photos are clearly not of the same thing taken from different angles, because the background in each is very, very different.

[meteorite-list] Look Out Below! Metal and Meteorwrongs
For anyone interested in Meteorwrongs Greg S. http://www.forteantimes.com/features/articles/4021/look_out_below.html Look Out Below! Metal and Meteorwrongs Mystery metal chunks and meteorites that aren't what they seem to be By Peter Hassall July 2010 Meteorwrongs MYSTERY METAL Odd bits of metal have fallen from the sky for centuries, as Charles Fort recorded in his books. Today we have possible sources such as satellites and high-flying aircraft that did not exist in Fort’s time, while some recent apparent falls have boasted an industrial origin. Al Smith was shifting a sofa with a forklift in his moving company’s warehouse in Jersey City, New Jersey, on the morning of 18 February 2009 when a brick-sized chunk of hot metal smashed through a wooden roof beam and shelf right next to him. After an examination, the Federal Aviation Authority (FAA) said the object was not from a plane. It was suspected to have been ejected from a mulching machine somewhere in the vicinity. A shaken, but unhurt, Smith was planning to buy a lottery ticket. [1] A week later, a 2.7kg metal chunk smashed through the roof of a Buford Drive, Southeast Oak Cliff house. Luckily nobody was at home. Dallas police confirmed it was a piece that had flown off a grinder at the nearby Big Bird Tree Service. [2] But not all metal falls can be explained so easily. On 26 February 2009, a mystery piece of something smashed Richard Orsot and Linda Lang’s 1995 Isuzu Trooper SUV, wrecking the dashboard and partially melting the windscreen. “There was a loud explosion and bright light,” said Orsot, aged 61. “It was a big kaboom,” added Leroy Bolls, a neighbour, “like a sonic boom, but real close.” Mike Birondo, a fire investigator, was puzzled: “I can’t make heads or tails of it because I haven’t experienced something like this,” he said. “Whatever it was hit with some force and had some heat to it.” [3] On the night of 13 May 2009, residents of a town in western Kazakhstan saw two silver objects fall out of the sky. The silver balls were 60cm in diameter, had a silvery surface with what appeared to be a small opening. Attempts to break them open with tools failed to dent them. Aleksandr Ivanov, head of the local emergencies service, said they were most likely “fragments of a man-made aircraft”.[4] METEORWRONGS There are numerous reports of strange rocks being found on the ground coincident with a recent fireball sighting or meteor shower. In almost all such cases, despite the sincerity of the finder, the alleged meteorite turns out to have a more earthly origin. There are also some reports in which it seems likely that the finder has deliberately dreamt up a story about witnessing the fall of a fiery object to tie in with an unusual rock that they have found. Unfortunately, it appears that the report of 14-year-old Gerrit Blank being hit by a tiny meteorite falls into this category (FT253:10). Adam Weiner has used basic physics to figure out that the alleged meteorite would not have had a “velocity sufficient to induce enough compressional heating to produce a flash of light”; nor could it have created “an impact crater a foot in diameter”.[5] In fact, the alleged crater looks remarkably like a filled-in pothole! On 13 August 2009, Carlene Walker of Luella, Texas, found two rocks that she suspected were meteorites. She got in touch with several local experts to check. Then, after finding a third similar rock in her backyard, she met with local geologist John Moody, who examined the rocks. “I can’t say yes or no. All three rocks look similar, and parts of each have turned to glass,” he said. “Because glass is a super-cooled liquid, using a hand lens on the more polished-looking parts of the rocks reveals waves in the surface, a sign that parts of the rock have vitrified, or turned to glass. It’s almost like waves. They’ve been subjected to a great amount of heat. These are not like something you’d just find around. Volcanic slag can be like this, or slag from refinery places,” Moody explained. The first two rocks were found within 3m of each other and the last was found behind the house. Moody said the house was far from the road and behind a tree line, making it difficult for anyone to have thrown the rocks onto the property. The house was also some distance from the railway line, where similar rocks were used on the tracks.

The unusual rock was black, 6 by 4cm in size and gleamed like crystal. “I saw it on the ground near our back door – there were burn marks all over it. I’ve never seen anything like it before. It was dark and shiny,” he said. “Josh is so excited, it’s quite incredible really and it’s exciting to think how far the rock has travelled. I told them to take photos of

Re: [meteorite-list] Meteorwrongs
Hi Greg and List, I have a meteorwrong collection that is slowly growing. The only notable wrong that I am missing is Shirokovsky. Most of my wrongs turned up in large bulk shipments of unclassified meteorites. My collection of wrongs used to be larger, but I sold most of them last year.

I don't collect wrongs, but have a few of them. I'm happy to be able to say any I have seen (minus the pallasite looking one) I have been able to tell from looking at them they are not meteorites.

Re: [meteorite-list] Meteorite 20 Questions - Answer and Share if youDare. :)
Having a few spare minutes, and reacting as did Al Mitterling, I offer the following: (for entertainment purposes only; the following is the opinion of my home institution or, possibly, any other rational body...) | | 1) When did you start collecting? (how long ago) 3yrs? About. (or maybe, ten years ago, see below) To create a class on solar system genesis with actual examples. | 2) What first interested you about meteorites? The presence of serpentine minerals, indication that water was present on the parent bodies (please note this is dominantly in HED class). Something I am interested in is the link between ultramafic rocks, serpentinization and tectonic emplacement, and the ecological and social implications/benfits, etc. of serpentinites. Also, they represent samples of mantle materials that are impossible to obtain on Earth (core-mantle boundary, etc.) | 3) What was your first meteorite purchase, and from whom? Bassikounou, Michael Wilde, because I think it is a beautiful stone (no serpentinites, though) | 4) How many meteorites or localities do you currently have in | your collection? Probably 400 localities, I don't keep track, Microsoft Access does. | 5) If you had to know for insurance purposes, what do you | value your entire collection at? - in dollars - ballpark | figure OK, or just say none of your business. A lot. Too scary to think about, and I don't think they'll pay off anyway. (Not in the class of six or seven figures, like a dealer or anything, though) Wy past my budget for aforementioned class. | 6) What is your favorite meteorite and why? D'Orbigny, because I can't pronounce it and it might be from Mercury (oh, no, let's not start that thread up again...) and Mercury is my ruling sign. (oh, wait that's sooo seventies..) Actually, I'm lying, I can pronounce it, I can even pronounce Muonionalusta, although I can't pronounce Eyjafjallajokull, I'm not even sure I can spell it (or anything in Gaelic, for that matter..) Bassikounou, because for some reason I can't explain, I just like the way it looks. I guess. I don't really have a favorite, they are all specimens to me(sacreligious as that may be to a collector...) | 7) Have you ever found a meteorite in the field? Yes, in 1999 on a glacier in the high Arctic in Canada (oh, wait, did I just type that? The Mounties'll be after me now...). Really, it was legitimate scientific research; I was there to collect a thermochron sequence to date the uplift rate of the Princess Margarets, and we were discussing the igneous provinces (as I recall we were in the Jurrasic at the time). I picked up a rock on the glacier, wondering how it got there. Later, someone pointed out that things on glaciers are likely to be meteorites, having fallen there. (It's a small one, like a little pebble...don't get any ideas). On second thought, maybe I didn't find it there... We got in enough trouble over stealing Canadian intellectual heritage on that trip Did visit the Devon site where they tested the Martian rovers, though. That was pretty cool. | | 8) Did you ever get the deal of a lifetime on a meteorite? | If so, what was it? Don't think so. Pretty close to retail for everything. Except maybe an Odessa chunk that I got a pretty good deal on. I've had a few kind contributions, but I didn't seek them, so they weren't 'deals' I guess. Apparently gave the deal of a lifetime once... | | 9) Did you ever go through the ordeal of a lifetime to obtain | a meteorite? If so, please explain. Getting back from the glacier was an ordeal. A supposed 12 mile trek was more like 25. The running gag was, we need to make it back by nightfall (this was July at 80° N lat.). We went up and down mountains, down a 200 foot talus slope at the bottom of which was a glacial river that we rolled 800 pound rocks into that vanished instantly beneath the glacier (don't fall in...). One of the field team twice fell into arctic streams where we had to go fish her out; at one point the team leader led us into a box canyon which ended in a basalt dike that we couldn't get around, cut by the glacial river that we couldn't cross, so we had to climb back up the mountain to get around the canyon (after that, I led, as I had the GPS). This story does go on, but it occurs to me that this is just getting back, not actually an effort to find a meteorite, so I'm not really answering the question... | | 10) Have you ever consumed meteoritic material? (If so, how | or under what circumstances?) I am made of meteoritic material, aren't you? But, no, I don't eat my specimens (wouldn't that be cannibalism?). | | 11) Does your spouse share your meteorite passion, is | ambivalent towards it, or resents it? She has no problem with it, but isn't particularly interested (she is also a scientist, but with a somewhat different focus) | | 12) Have you ever let a bill go unpaid or late to buy a meteorite? (which Bill? Kies'?) No, of course not,

Re: [meteorite-list] Gebel Kamil webpage
Hi all, I'm fairly new to meteorites but I do know a bit more about photographs. Quite a couple of times I have looked at different images of the same meteorite and thought at first glance they were different specimens. The image in the rocky area might be an image of how the meteorite was originally found, then the rocks might have been moved and the area cleaned up including the sand on top of the rock. A bit of grooming to make it pretty for the photo perhaps. If you turn the rocky image 90 degree anti-clock wise and the clean one 90 degree clock-wise it seems to be likely the same rock, the first one being shot from above (see GPS facing the viewer and the overall angle now looking much more appropriate). If you then carefully study the surface structure and keep in mind the angle difference it seems quite likely to be the same individual. Good night everyone, Regine --- Jason Utas meteorite...@gmail.com schrieb am Do, 29.7.2010: Von: Jason Utas meteorite...@gmail.com Betreff: Re: [meteorite-list] Gebel Kamil webpage An: Meteorite-list meteorite-list@meteoritecentral.com Datum: Donnerstag, 29. Juli, 2010 17:21 Uhr Hello Bernd, Svend, All, 1) The background for each photo is significantly different. One is loose sand. The other, large rocks. The photos were therefor not taken in the same place. 2) The photo on the left is pretty clearly the iron before it was moved. It's well-embedded in undisturbed ground. The photo on the right...maybe not. We can't tell if that iron is sitting on the ground (so it could have been moved there). 3) If we're to assume the photo of the iron on the right is of the same iron, we have to wonder about why they would have removed it from its hole (on the left), moved it to a rocky area (photo on right), put some soil on top if it (note that it's clean on the left), and then took another picture of it, with a GPS next to it, as though they're recording a find location. Of course, the GPS could just be for scale, but since they didn't use a GPS for scale purposes with the left hand (clearly in-situ) photo, it seems unlikely that they would then use it exclusively for scale purposes after moving the iron. -All the less likely because the first photo shows a fairly wide angle - and there are *no* rocks nearby. I suppose you could count this as circumstantial evidence, because the iron could have been exhumed, moved, covered in dirt, and then photographed, but this seems very unlikely. Regardless, the photos are clearly not of the same thing taken from different angles, because the background in each is very, very different.

Re: [meteorite-list] Gebel Kamil webpage
Hello Regine, All, While I agree that the overall shapes of the irons are similar, and concede that you probably know more about photography than I do, I do know much about in-situ photographs and desert terrain. The trouble with assuming that the photo on the left is a cleaned-up version is the following, which I'd like to condense and then apply. #1 Photo 1: meteorite 1/2 buried Photo 2: meteorite on surface #2 Photo 1: meteorite clean Photo 2: meteorite covered in dirt #3 Photo 1: meteorite in undisturbed soil, surroundings Photo 2: meteorite on surface, may have been moved (dirt/rocks on surface would suggest otherwise, but possible). Surroundings themselves look undisturbed. #4 Photo 1: meteorite in sandy area, small rocks Photo 2: meteorite in rocky area So, #1. The photograph on the left shows a meteorite well-embedded in the ground. And the surface soil has been moved in only two locations around the entire meteorite (#3). There is a left-handprint that clearly breaks up the uniform texture of the undisturbed ground in front of/to the left of the iron, and it looks as though someone poked the ground a few inches in front of the pen used for scale. The rest is undisturbed desert pavement. If you were to step on it, you'd change the surface -- and it won't be the same until after the next rain. Apply #4. They clearly didn't move the large rocks from around the meteorite on the right because the ground around the meteorite on the left is almost entirely undisturbed. The meteorite on the left is undisturbed as well (and it's half-buried, as opposed to being on the surface); compare to the photograph on the right. Both meteorites have tapering ends. But in the photograph on the right, the tail-end is clearly several inches above the ground. The photograph on the left shows no such thing. That meteorite (on the left) is really sitting *in* the ground, as opposed to on top of it (again, compare to right-hand photo). I suppose you could chalk this up to an optical illusion, but I really don't think that it is. Take a look... Again, the meteorite on the left is half buried, yet clean, and in an undisturbed, rock-free area. The meteorite on the right is sitting on the surface of the ground, is covered with rock and dirt, and is also sitting in a relatively unaltered bit of desert. This is what happens if you step on similar ground. http://vormedia.com/images/mono2037.jpg http://media1.z2.zoopy.com/media/2009/05/20/7304/42304/original.jpg Compare to each meteorite photo. They're both sitting in pretty pristine desert. Not even a footprint. It's a textural thing. If you're saying that they cleaned up the photo on the right to make the one on the left, you're going to have to explain why they wanted to bury the iron deeper into the ground than it was in the first place, how they did so without disturbing the desert pavement in the immediate vicinity of the meteorite, and how they removed the rocks and made the new surface look as though it had never been disturbed. I've taken far too many in-situ photographs of meteorites in desert conditions; even stepping on a hard-pan lakebed can leave visible traces in photos. Both photos on this site show the meteorite(s) in undisturbed terrain, and yet one is sitting in the ground, and one is sitting on top of it. If we are looking at two photos of the same meteorite (which I doubt), the meteorite must have been moved, but if it was, it was from the left photo to the right photo. And whoever was carrying it was able to set it down without even stepping on the ground visible in the photo. It's hard to do that when you're carrying nearly 180 pounds. I have no agenda/reason for saying this; it makes no difference to me whether or not there are one or two such irons. But I'm seeing double, and they really don't look like twins.
