Some sharp metal protrusions at Tucson: Handling an OC at Tucson a blade of metal stuck in my hand and drew blood. On closer examination it was apparently a shock melt surface which differential erosion had left sharp and sticking out. I also saw a nice Chergach which was broken on a shock melt surface which looked much like "slickensides." Again, the surface was metal. Both are interesting features of the "whole rock" that are not readily imaginable from cut slices. Cheers, Nick Received on Tue 05 Mar 2013 05:48:18 PM PST |
