Hello folks, My 18.3-gram specimen of Dean's NWA 4755 diogenite was in the mailbox today and I can tell you it is a beauty! Thank you, Dean! Friday, August 31, I wrote it may be paired with NWA 3143. Now that I can see it in person beside my piece of NWA 3143, I'm pretty sure these two are paired.
I also wrote that Dean's picture showed an area where beautiful hypersthene crystals met in triple junction. Now that I have this piece before me, a closer look through the micoscope reveals that this is one "huge", green hypersthene crystal measuring 8 mm (!) in widest dimension. It almost looks like it was a "Tatahouine inclusion." The Met.Bull. database describes NWA 3143 as having a "translucent" interior,...something I did not quite understand but my NWA 4755 from Dean clearly shows this phenomenon: when viewing it from a proper angle, you see what looks like a thin matte, silvery coating. BTW, Dean still has some smaller pieces for sale here: http://www.meteoriteshop.com/metsale/diogenite.html Best wishes, Bernd ______________________________________________ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
