What is a thin section?       What do all the colors mean?    
Thin section between crossed polarizers.   Angrite

TKW 107 grams. Fall not observed. One stone covered by fusion crust was purchased by Luc Labenne in Tucson, AZ., in 2011.

Info about angrites here
 


Anne writes:
NWA 7203 is a quenched angrite from a surface or near surface magma on the angrite parent body. The composition of the fine-grained feathery features is olivine (colored) and plagioclase (white to gray). The texture is a result of rapid cooling of the magma.
