Re: [meteorite-list] Where are the thin section experts?
Hi all, Carl suggested that I list everyones guesses as to what they think this meteorite will be classified as. Here is a partial list, (as I will be adding to it ) many meteoriticists and collectors have seen this stone, here are some of the brave souls that have dared to venture a guess. Come on make a guess if you haven't already. If I have misquoted your guess or you would like to add (or change ) a guess please let me know.

Re: [meteorite-list] Where are the thin section experts?
Hi Ruben and List members, My eyes are calibrated for Lunaites right now having just returned from a Mojave hunt. I trained my eyes before the deep desert trip in hopes of actually finding one. After hiking 62 miles last week, I did find a few breccias, some fossil camel bones, an ordinary chondrite and maybe a weathered carbonaceous chondrite. We even found a stolen vehicle from Utah stashed in a box canyon which we reported. The police dispatcher was not ready for exact GPS coordinates though. With my eyes still calibrated in hopes of finding a North American Lunar, my first guess is a Mesosiderite. With that said, I am certainly no expert on thin-sections but do enjoy observing them. I looked for triple-junctions and did not see any in the thin-section image so I do not believe it to be anything primitive like a Winoniate, Lodranite or Acapulcolite. I see no relic chondrules either. If the opaque areas are metal or oxides and not chromite, then there seems to be too much for a Diogenite. That's what makes finds like Ruben's exciting, you do not know what you have until the minerals are recognized in a laboratory. In any case, it is indeed a rare find. My blistered feet are testimony to how difficult any meteorite is to find, congratulations! Please let us know what the laboratory reports, Best Regards, Adam - Original Message From: Ruben Garcia mrmeteor...@gmail.com To: Meteorite List meteorite-list@meteoritecentral.com Sent: Mon, October 26, 2009 4:02:55 PM Subject: [meteorite-list] Where are the thin section experts? Hi all, The disclaimer: My main purpose for posting this is because I know very little about achondrite meteorites. This is because (as a general rule) I only collect what I find, and though I've found lots of meteorites this is my first achondrite find. As most already know this find is currently being classified by Laurence Garvie at ASU. However, while we wait for the official classification I thought it would be fun and enlightening to show the section and see if the guesses change from before. It would be great to hear from some of the great minds on this forum - Ted Bunch, the Hupe's, etc.. - but any ones guess is welcome and interesting to me. According to the (4) meteoriticists that have seen the thin section - it is NOT a pallasite or chondrite. However, no one can definitively ID this meteorite instead they gave a few guesses - primitive achondrite like. This thin section was pictured with a home made cross polarized light set-up I made. It’s not the best but I hope it's good enough to give an idea.

[meteorite-list] Where are the thin section experts?
Just like Adam, I've been desperately looking for triple junctions, ... none :-( Unless it is something anomalous my recent guess (olivine diogenite) is wrong because diogenites do have triple junctions! I've been looking for chondrules or fragments of chondrules, ... none :-( Metal-rich + absence of chondrules, does that look like a CH or a CB? I would expect to find chondrules in a CH chondrite and I would expect to find larger pyroxenes in a CB chondrite (just think of Gujba, for example!) *If* the interference colors are correct, this thin section is excessively rich in brownish pyroxene, and, another *if* it is orthopyroxene, we might be looking at a metal-rich (anomalous) aubrite.

Re: [meteorite-list] Where are the thin section experts?
Adam, Bernd, Greg, and List members, Adam, thanks for posting your guess and congratulations on your recent finds. You say you are no expert (with thin sections) but I know that you have seen more than a few rare meteorites – your opinion is valued! I have been hitting the dry lake beds nearly every weekend (mainly in winter months) for several years now, and while I’ve made some great finds I’m sure this will be my best. Sonny and I join you, (along with a few others) in the race to see who will find the first American lunar. It will happen, in fact he and I already have lunar looking (at least to my untrained eye) contenders. Bernd, You too have seen and know a lot more about rare meteorites than I and yes I am learning a lot from all the responses. Greg, As to your question about scale the thin section in on a regular sized (thin section) slide and in the picture the edges can be seen so that should give an idea. -- Ruben Garcia (Mr-Meteorite) Website: http://www.mr-meteorite.net Articles: http://www.meteorite.com/blog/ Videos: http://www.youtube.com/profile?user=meteorfright#p/u __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
