What is a thin section?       What do all the colors mean?    
Thin section in cross-polarized light.   Diogenite

TKW 485 grams. Fall not observed. Purchased 2005 in Morocco.

John writes:
NWA 2824 is a highly shocked achondrite probably from the Ibitira parent body. It is 18 percent plagioclase, the white zones in these photos. The plagioclase has a spherulitic texture, clusters of fine radiating laths, from crystallization from a melt. Here the melt is presumed to be from impact shock.

Fields of view are 3mm (photo 1) and 0.5mm wide.
