Dear List Members, This week we would like to introduce NWA1292, an Ultra Rare CO3.6. There is only one other CO in existence with this subtype! NWA1292 Exceedingly Rare CO3.6 Meteorite Northwest Africa 1292 (provisional), a CO3.6, Fa1-38, S1, W1 Ornans type carbonaceous chondrite found 2001 in the Sahara desert. Two stones where found for a Total Known Weight (TKW) of 136 grams. One of the two was sent to UCLA who classified it as a CO3 with no subtype. Another specimen was sent to NAU who assigned a subtype of 3.6 based on similarities to Warrenton, the only other CO3.6 in existence. NWA 1292 is a fresh and beautiful example of an exceedingly rare subtype so if you are into collecting by type this may be your only opportunity to add a very fresh CO3.6 to your collection. For your perusal we included the provisional separate entry submitted to the NomCom below: Northwest Africa 1292 (provisional) Morocco Found 2001 Carbonaceous chondrite (CO3.6) Two very fresh, crusted stones (total weigh, 136 g) were purchased in Erfoud, 2002. Classification and mineralogy (T. Bunch and J. Wittke, NAU): typical CO component assemblage, although chondrule and mineral grain outlines are less sharply defined with somewhat higher abundance of ~0.05-0.1 mm sinuous-rimmed, spinel-rich CAIs. Mean olivine composition is Fa37.4 with a range of Fa37.1 to 37.8, N=18; Ni, 0.05-0.10 wt % and Co, 0.3-0.07 %. The metamorphic subtype of CO3.6 is based on the textural similarities with the Warrenton CO3.6 meteorite and its olivine composition of Fa38.6 (38.3 - 39.1). Weathering grade, W1 (slightly iron stained with low metal oxidation). Specimens: 20 g, NAU; main eBay Link: http://members.ebay.com/aboutme/meteoritelab/ Thank you for looking and if you are bidding, good luck.

Dear List Members, This week we would like to introduce some Martian material that is paired to NWA 480. All the we have are micromounts that we are starting out at 99 cents each. NWA480/1460 Martian Meteorite Northwest Africa 480/1460 is a Martian basaltic shergottite found December 2001 in Northwest Africa. NWA 1460 (provisional)(70.2 grams) is paired with NWA 480 (28 grams) giving a Total Known Weight (TKW) of only 98.2 grams. Virtually all of NWA480 has been committed to science so NWA1460 is all that is available. We managed to get a few fragments when we were in the process of purchasing NWA1460 from a Moroccan dealer. We donated most of the fragments to the University of Washington for study who informed us it was paired with NWA 480 and we kept the rest. The Maskelynite is clear and looked like diamonds to the Moroccan dealer who did not know any better. Being honest, we told the Moroccan dealer (Habbibi) what he really had and then he changed the agreement with us and sold to another collector for a much higher price. This meteorite is very fresh and looks as if it could have fallen months ago. We are starting these fragments out at .99 a gram and will let the market decide what they are worth. We have an extremely limited amount of material so now may be the time to place a bid. eBay Link: http://members.ebay.com/aboutme/meteoritelab/ Thank you for looking and if you are bidding, good luck! We will be intoducing another stone later this week.

Re: [meteorite-list] Ad -Rare Weekly Material Special
Hello Adam and List, NWA 1235 caught my interest earlier this year when I read the abstract you referenced. With help from a friend I was able to acquire a small specimen and construct a webpage based on information from this abstract. BTW, contrary to the statement in this abstract that only NWA 1235 and Y-82189 have been found to contain phlogopite, it was reported that the CV3 chondrite Grosnaja contains sodium phlogopite as mentioned on my website: The Bali-like mineralogy of Grosnaja includes the phyllosilicates saponite and sodium phlogopite replacing Ca-rich minerals in chondrules and CAIs. I look forward to further research results on NWA 1235. Sorry about the difficulty in linking to my page. It was only after the 5th case (that I am aware of) of somebody using my texts verbatim on their commercial website (making it a violation of the Digital Millenium Copyright Act) that I was compelled to install an HTML protector program. This is more trouble for me to use, but gives me some degree of satisfaction knowing that these vultures (as you so succinctly put it) will now have to type out the texts by hand to steal them. The page URL still appears in the address bar and you'll notice that the previous page name is now simply preceeded by protected_. I've always given permission to use my compiled texts when asked, only requesting that a credit to meteoritestudies.com be given on the page. In the future, if anyone on the List wants to use my texts, just ask and I'll provide a usable copy. David Adam Hupe wrote: Dear John and List, Good questions because I personally thought that mica has never been found in a meteorite. I will ask scientists more questions regarding this very odd meteorite. David Weir's site has a discussion regarding NWA 1235 but I cannot provide a link because he had to protect his site from vultures who were using his material on their own web sites.

John Dear List Members, This weeks rare material special is NWA 1235, a strange ungrouped Phlogopite-bearing Enstatite achondrite. It is classified as an ungrouped Phlogopite-bearing Enstatite Achondrite, in other words a unique one-of-a-kind meteorite with a Total Known Weight (TKW) of only 80 grams. We were lucky to get a few grams of this material in trade for some planetary specimens so it was not an inexpensive acquisition. We are keeping the largest piece for our collection and are offering the rest. This meteorite is even odder than NWA 011, which garnered a lot of press in the last couple years after speculation it may have originated from the planet Mercury. Just like NWA 011 the parent body is unknown. It will be interesting to see where the O-isotopes place it. We were told the finder is keeping the rest in his collection so very little will be available so now may be the time to bid. We are starting all of the NWA 1235 specimens out at just .99 and will let the market decide their value. In this weeks auction we are also introducing nine never before offered meteorites. To see these just look for NEW in the title and to see this week's special look at NWA1235.

Dear List Members, This weeks rare material special represents an outstanding benchmark meteorite. As a matter of fact, we searched thousands of meteorites before coming up with this one. We were lucky enough to acquire this stone while looking at a nomad's offerings in the village of Safsaf a year ago. This expedition was published in the February 2003 issue of Meteorite Magazine, see cover story. This week we would like to introduce NWA 1756: NWA 1756 LL3.0/3.2 Benchmark Meteorite NWA 1756 is a primitive LL3.0/3.2, W1/2, S1 chondrite found October, 2002. It may be the most pristine ordinary chondrite ever found with the possible exception of Semarkona which is off limits to collectors. The reason we say possible exception is that when comparing apples to apples and not apples to oranges this meteorite plots cleaner than Semarkona (LL3.0, W0, S2) according to one published method used for classifying low petrologic types. Note in the chart below that every point for NWA 1756 is within the 3.0 box. Also note that the red plot points (NWA 1756) are constrained to a much smaller area than Semarkona in the diagram suggesting less metamorphism. Petrologic chart link: http://www.lunarrock.com/nwa1756/nwa1756.jpg NWA 1756 was submitted as a pristine LL3.0 by two well-known scientists with over 50 years combined experience in meteoritics. The chondrules where carefully compared to those in Semarkona, were charted and were found to be virtually identical. This represented an enormous undertaking by scientists. As we understand it, the reason given for the LL3.0/3.2 petrologic range was that the published chart did not show the difference between a 3.0 and a 3.2. If this given reason is correct, the argument does not hold weight because if you look at the chart it assigns Semarkona a perfect 3.0 yet NWA 1756 has a tighter plot meaning it is less metamorphosed than Semarkona according to this published method. Adding to the problem is that there are several systems in place to determine extremely low petrologic types, which few seem to agree on. As we understand it, since NWA 1756 has a weathering grade of W1/2 (lightly weathered) some of these methods can not be used to accurately determine the petrologic type meaning some other system will have to be used. We are not worried about this because this stone will be studied in every conceivable way because of its scientific importance. Also a few exceedingly rare minerals have been found that do not exist in chondrites with the slightest degree of metamorphism. It is our belief that meteorites like this will help develop standards furthering the knowledge of meteoritics. What does this mean? We do not know because there are only a few meteorites in the world that this can be compared to. Many scientists consider Semarkona to be the most unequilibrated chondrite that exists, meaning NWA 1756 will be compared directly to it. We feel, when equal testing procedures are performed, the well-studied Semarkona may be determined to be less than pristine when equal standards are applied. After all, the 3.0 designation means perfect unequilibration and NWA 1756 shows no signs of metamorphism and is not shocked with a rating of S1 compared to S2 for Semarkona. Another issue is the xenoliths found in Semarkona, what petrologic type are these, perhaps a 3.5? Does this mean that Semarkona is really a LL3.0/3.5, W0, S2? Clearly, all these issues are open for debate and it will be exciting to see the final outcome. We do not claim to be scientists and are expressing our opinions, which are shared by those more qualified than ourselves. We asked a lot of questions regarding NWA 1756 so that we could hopefully present our views in a well-informed and accurate manner. For your perusal we included the description found in the 88th Meteoritical Bulletin below: Northwest Africa 1756 Morocco Found 2002 Ordinary chondrite (LL3.0/3.2) A 68.2 g meteorite was purchased in Safsaf, October, 2002. Classification and mineralogy (T. Bunch and J. Wittke, NAU): monomict chondritic breccia; chondrules are very similar to equivalent chondrules in the LL3.0 Semarkona chondrite in terms of phase/mesostasis compositions, zoning profiles, and textures. Type IA olivine: FeO = 0.21 to 1.94 wt%; CaO = 0.31 to 0.51 wt%. Type IIA olivine: FeO = 11.8 to 15.9 wt%; CaO = 0.10 to 0.19 wt%; P2O5 = 0.09 to 0.36 wt%; Chondrule mesostasis is optically isotropic. Matrix metal is Ni-rich (50 to 60 wt%) and occurs in metal-pyrrhotite-haxonite ± magnetite, chromite, carbon, cohenite, 0.1 to 0.2 mm aggregates; metal contains small (1 µm) SiO2-rich inclusions. Shock level, S1; one xenolith is S4; weathering grade, W1/W2. Specimens: type specimen, 12.5 g and 2 thin sections, NAU; main mass, Hupé. Enough of the qualifications, this is one awesome meteorite that scarce few collectors will be able to add to their collections. With 68.2 grams minus two thin section cuts and a 12.5-gram type

Dear List Members, In in effort to get back on track with the weekly rare material specials we would like to introduce NWA 969. NWA969 LL7 Meteorite Containing Bottled Water? Northwest Africa 969 is an extremely rare LL7 type chondrite with fluid trains found in June of 2001. What makes this chondrite so interesting is that it was first mistaken for a Brachinite. Its composition, ratios and 120 degree triple junctions appeared identical to that of Brachina. The few differences being sparse oriented intergrowths (interpreted as relic chondrules) chondrules and actual trains of fluid in the olivine. Only after exhaustive testing and oxygen isotopes was it determined to come from the LL chondrite parent body. More interesting is the way the fluid (water?) is trapped. It is contained in small round cavities in the olivine grains forming bubble trains, which can be observed with a microscope in thin section. We refer to this fluid as 4.5 billion year old bottled water. Although water has been found in a few other chondrites, it was contained in halite (salt) crystals not cavities in olivine making this a unique meteorite. For more information we have included the separate entry found in the 88th Meteoritical Bulletin below: Northwest Africa 969 Morocco Purchased 2001 June/October LL7 chondrite A small stone was purchased from a Moroccan dealer by A. and G. Hupé (Hupé) in 2001 June, and subsequently seven more stones were purchased bringing the total weight to 463 g. Classification and mineralogy (A. Irving and S. Kuehner, UWS): Genomict breccia consisting of angular clasts in a finer grained matrix. Mostly olivine (Fa30, FeO/MnO = 57.7) exhibiting 120? grain junctions, with subordinate interstitial troilite and Fe-Ni metal (30% Ni), and accessory orthopyroxene (FeO/MnO = 37.6), chromite, chlorapatite, interstitial sodic feldspar (Ab85Or5), and fine-grained intergrowth patches (probably former melt or mesostasis). Silicate minerals contain trains of fluid inclusions. Rare relict chondrules are present. Oxygen isotopes (D. Rumble, CIWGL): analyses of two whole rock fragments by laser fluorination gave ?18O = +5.3 ? 0.1, ?17O = +4.0 ? 0.1, ?17O = +1.22 ? 0.03 per mil. Specimens: type specimen, 20 g, and three polished thin sections, UWS; main mass, Hupé.
