I'm pretty sure that it is a huge chondrule or mega-chondrule. These are not common, but you can find them from time to time, especially in L6 material. Have a look at my website, and at the picture on the lower right on the following page (click the photo to load up a larger image): http://www.meteoris.de/basics/class2.html This is a nice 10x8mm mega-chondrule in L6 chondrite HaH 173, and it has virtually the same size as the "object" in your sample. BTW, if anyone is interested, I still have the sister slice of this one for trade or sale (with only 7x5mm for the mega-chondrule, though, but with a neat 5x3mm troilite blob, too). Pictures and specifications on request. Best, Norbert __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Hullo, Further to the threads regarding mega chondrules and odd inclusions, Marc Fries of the Geophysical Laboratory at the Carnegie Institution of Washington is going to have a look at my Allende inclusion and hopefully explain what the heck has gone on here! http://homepage.ntlworld.com/entropydave/inclusion.jpg Naturally (with Marc's explicit permission, of course!) I will share the results and hopefully we'll have a good idea of what's happening in this odd slice!! Also, on the subject of Marc, who did a lot of work on the petrogenesis of Portales Valley (and amazing work too, BTW) I am pleased to announce that I hope to get my first slice of fat and veiny PV soon, weighing in at a (for me) hefty 28g thanks to Illinois Steve and Fleabay! Now that IS an odd meteorite!! And congrats to Martin A. and Stefan R. on their new lunar NWA 4483 - it is a wonderful fresh looking specimen! Buy Buy Buy!!!

Re: [meteorite-list] Mega-Chondrule
Hi Marcin,
Good thread! NWA 2892 is a hard one to beat for Macrochondrules! This slice
has a 13.5mmx11mm chondrule.
http://www.meteorites.com.au/favourite/august2005.html
And NWA 4040 has some very large pale ('bright') inclusions. This one is
38mmx28mm at widest points.

Cheers,
Jeff

If we are at this very interesting topic, maybe we make a little competition
?
Who have the biggest:
a) complete chondrule (Gujba rulez ?)
b) strange inclusion (exclude breccia fragments ofcourse)

A) My chondrule You know, I have the mirror slice of this one from ebay.

Hello List, This is a piece that I thought was considered duel lithogy, but I was told by a pretty relible person that the dark part is an inclusion, maybe even a chondrule, or a "DI" Dark Inclusion. The first link is to a photo of the main mass cut in half. The second link shows multiple photos of each half. This is a very interesting piece. The full stone was 163.8 grams. The dark part (chondrule,or incllusion,or different loithogy) covers about 40-45% of the stone.The 2 halves.http://illinoismeteorites.com/images/duellith5.JPGMultiple photos of each stone, main mass, and descriptions.http://illinoismeteorites.com/saharanmeteorites.htmThanks,Joe Kerchner,http://illinoismeteorites.com- Original Message From: Jeff Kuyken <[EMAIL PROTECTED]>To: PolandMET <[EMAIL PROTECTED]>; meteorite-list@meteoritecentral.comSent: Monday, October 23, 2006 3:49:56 AMSubject: Re: [meteorite-list] Mega-ChondruleHi Marcin,Good thread!

Re: [meteorite-list] Mega-Chondrule Competition
None of these are in the "mega" size range, but IMHO there are some really interesting chondrules here. This unclassified slice is something that I bought as a "buy it now" item for 4 or 5 bucks from a seller just because I was already buying other things from the same person, and thought that I might as well take advantage of the lower combined shipping. Turns out, though, that this "impulse buy" piece is one of the favorites that I own As for scale, it jams tight in a 38mm membrane box. There is one especially interesting zoned, multicolored eggish-shaped one in the right lower quadrant of the scan: http://webpages.charter.net/garrison6328/tmp/cool_unclassified.jpg __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

About all that I can handle in identifying mineral species in meteorites is "this looks cool" and "that looks odd". It seems pretty obvious, though, that this has a pretty darned low metamorphic grade, and that the chondrules (and possibly inclusions deserving other names) have had a pretty complex and diverse history. There is NO visible metal in it, but there are areas where it is apparent that metal has oxidized away. That could be from long terrestrial weathering, or it could be ancient, I don't know. The redness of the matrix does resemble some "R" chondrites to me. I've made a map of some of the features that interest me: http://webpages.charter.net/garrison6328/tmp/cu_map.jpg the "zoned, multicolored" one I mentioned is number 2, of course. It is a similar size to other chondrules in the piece, so I don't know about the alien clast thing-- unless it came from something with much smaller chondrules. As for the possible CAI, you mean in number 3? I donno. It has white areas and also blueish ones and reddish ones. Lots of complexity there. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
