Apart from the chondrule metropolis there are many other = inclusions and/or clasts. In my 11.8g slice I can see: - Around 1-2 troilite inclusions per sq cm. - Reasonable amount of visible metallic iron. - Armoured (with troilite) chondrules. - Armoured (with metallic iron) chondrules. - Carbonaceous inclusions? - Achondritic inclusions/clasts? (the big inclusion looks almost like a = howardite with dark angular fragments) - Barred chondrules What's going on here?!? Maybe someone could also explain how you get an = LL3 with achondritic type inclusions. Is this even possible? (It has a = shock rating of 4 too.) There are some links below to scanned images. = They don't do the piece justice but are better than nothing and are = fairly large too. http://www.meteoritesaustralia.com/images/NWA 3099-1.jpg http://www.meteoritesaustralia.com/images/NWA 3099-2.jpg There are more photos also on Stefan's page: = http://www.meteoriten.com/special.html I would certainly appreciate any opinions on this beauty.
