[meteorite-list] Ad - NWA3118 With Chondrule Field!
I recently donated two pieces of Allende to the Natural History Museum in Vienna: One had a featureless dark inclusion looking similar to the one seen in Rob's NWA 3118 slice featured in the 2004 December 1 Rocks from Space Picture of the Day, and the other one had a inclusion looking silmilar to the chondrule fild in the Hupe's NWA3118 slice. Still, the researchers said that this is a dark inclusion, and did not call it CM or CO xenolith. Any- way, they are working on it either.

Herbert, List, I did exactly the same, thus gave an Allende slice with an about 1+ cm diameter dark inclusion to a representative of the NH Museum in Paris about 3 years ago. He said the museum team would be happy to work more on. As far as I remember, I did not require a personal answer but mentioned that I will be happy to read one day their related publication. But we all know how long it can sometimes take for Science to get one small step forward... By the way, all my best wishes to all. Should this new year 2005 direct (at least) one small rock from space to everyone's backyard! Many trades in perspective!

Re: [meteorite-list] Ad - NWA3118 With Chondrule Field!
Howdy list I'm working with an inclusion just like this one in another sample of NWA 3118, and I'll pitch in here with my impression - it is not a CO inclusion. This material is a dark inclusion, and the one in the sample I'm looking at is probably a type B. There are reams of papers on dark inclusions, but for a good, quick overview have a look at this one: P. Buchanan, M. Zolensky, Nonporous silicate rims around dark inclusions in Allende, LPSC XXX Abstract 1830 This particular inclusion contains porous olivine grains and roughly spherical, heavily reworked mineral grains that might have been chondrules once upon a time. They seem to have been both aqueously and then thermally metamorphosed, and if anyone has a favorite theory on how they got there I'm all ears.

Forgot to mention this cool piece. NWA 3118 with what looks like a CO3 Chondrule Field? Pieces sent in for testing to the University of Washington and Carnegie.

Allende has CM type inclusions but I haven't heard of CO inclusions in Allende. I also have a piece on ebay which shows this feature. http://cgi.ebay.com/ws/eBayISAPI.dll?viewItemcategory=3239item=6502019056 -- Eric Olson ELKK Meteorites http://www.star-bits.com __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Ad - NWA3118 With Chondrule Field!
Rob Wesel made this statement: Looks exactly like the dark inclusion thread about a month ago, several scientists here and in Japan are working on it. Early unofficial thoughts are that it is solidified sediment, not chondritic. Have your UW group check in with Cascadia Meteorite Laboratory's Alex Ruzicka, may save some steps. My response: This is not an amorphos field but one that contains 1mm chondrules. Oxygen isotopes are being plotted for both lithologies so we should know if it is CM or what I suspect, A CO3. Here is a link to a piece I plan on selling, the rest has been donated to science. This image clearly demonstrates that chondrules are present in the field: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=6503275285 Kind Regards, Adam Hupe The Hupe Collection Team LunarRock IMCA 2185 [EMAIL PROTECTED] __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Hi Adam- Upon further review of the active auctions I must admit that it was one of the completed ones that reminded me of the dark inclusions. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemcategory=3239item=6500759588 That is the one I was thinking of, very irregular morphology and only at the periphery..but on closer inspection it does have different character than what I sent to CML/Japan. Another reason to get a hold of some of this material if you haven't already. The CV parent body is giving us all kinds of clues right now. Best of luck in this, looks cool.
