What is a thin section?       What do all the colors mean?    
Home made thin section.

Dave writes:
The making of the thin section is covered in a five page article I submitted to the May 2010 edition of METEORITE magazine (Vol. 16, No. 2). Basically, I cut a 1mm slice from a larger piece, glued it to a glass slide and ground it down to about 30 microns on a 600 and 1000 grit diamond lap.
