(For the few list members that have already assisted me in identifying the rock in question, these images are slightly better quality): http://members.cox.net/mojave_meteorites/Meteorwrong1.jpg http://members.cox.net/mojave_meteorites/Meteorwrong2.jpg http://members.cox.net/mojave_meteorites/Meteorwrong3.jpg http://members.cox.net/mojave_meteorites/Meteorwrong4.jpg http://members.cox.net/mojave_meteorites/Meteorwrong5.jpg The fourth image shows the windowed interior. I welcome any of our rock experts to offer opinions on probable ID -- gabbro, black granite, diorite, etc. Specific gravity is ~3.0, and rock has no paramagnetism. I was able to scratch the black surface with a pocket-knife; haven't tried the white inclusions yet. No streak on a streak plate. --Rob ______________________________________________ Meteorite-list mailing list Meteorite-list_at_meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list Received on Sat 09 Apr 2005 01:20:17 AM PDT |
