As some areas have chondrules that look very much like L3 or LL3 material (chondrules intact and sharply delineated with hardly any matrix in between), while have obviously undergone considerable metamorphism (chondrule rims blurred, low abundance of chondrules that are intact), we may also be looking at something like L3-5 or LL3-5 or even L3-6 or LL3-6 if Stefan's detail5.jpg is really a highly metamorphosed component. Matteo guesstimated it might also be an H chondrite. Well, the majority of chondrules seem to be rather small which might point toward a possible classification as an H chondrite, but, on the whole, H chondrites usually contain a smaller proportion of large chondrules than the L and LL chondrites. So I too, would assume it to be an L chondrite. But who knows? Only the classification will finally tell! Anyway, whatever it is, it's a terrific example of what the asteroid belt out there has in store for us, and, another example for why I personally think it is an untenable point if someone says NWA meteorites are less sought after than, well, say, historic finds with a pedigree. If this oval tree-ring beauty had geographic coordinates and a well- established TKW, would this add to or diminish its beauty and its extraordinariness? No, I don't think so. No flame wars, please, ... just my point of view ;-) Cheers, Bernd Received on Sun 13 Nov 2005 05:03:32 PM PST |
