http://www.rocksfromspace.org/November_14_2007.html Hello Jerry, Mark and List, NWA 4522 is not only very chondrule-rich with lots of sometimes very colorful medium- and large-sized chondrules (among them several so-called "bull's eye chondrules," officially called "bleached chondrules" like the one Jerry is inquiring about) but it is also a truly awesome breccia with some slices displaying large, creamy yellow clasts of seemingly lower petrologic grade (5 or 6). Other slices show gunmetal blue clasts that look mottled and suspiciously like LL6 or even LL6-7 inclusions and still others show cm-sized dark, featureless inclusions - almost CK-like with tiny "nuggets" of troilite. Well, when NWA 4522 was offered by Carsten some time ago, I was unable to decide which slice I should take so I purchased four of them and can now enjoy all these features simultaneously :-) Best wishes, Bernd ______________________________________________ Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
