OK, indulge me.  They say necessity is the mother of invention.  As you may have seen, I like to take micrographs of highly polished meteorite slices/hand samples.  I like this better than thin section examination because more often I have a cool looking meteorite and no thin.  This time I had a great Martian thin section on loan from Jim Strope but what do you know?  No hand sample.  Darn, I'll have to order one!

 

I tried out my thick sample techniques on this thin section by bonding a silvered strip of mylar to the back.  The results are interesting but please don't judge this technique on these images.  The results on cheaper, thicker thin sections was astonishing.  Maybe I need to order some not so thin, thin sections.

 

Once again, the thin section was a generous loan from Jim Strope.  http://www.catchafallingstar.com The information about NWA 998 is listed in the 160X group of images.
