Macroscopic Description: Kathleen McBride
Thick, ropey, black fusion crust covers the surface of this carbonaceous chondrite. The black matrix has mm sized light colored chondrules.

Thin Section (,2) Description: Tim McCoy, Cari Corrigan

PCA 02050 - Plane-Polarized Light
Plane-Polarized Light
The section consists of a few small chondrules (up to 1 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa0-40, with a peak at Fa0-2. The matrix consists dominantly of an Fe-rich serpentine; chondrules are relatively unaltered. The meteorite is a CM2 chondrite and pairing with PCA 02011/02012 is likely.
