Classification: Carbonaceous chondrite (CV3)

History: Purchased in April 2019 from an Algerian dealer.

Petrography: (A. Irving, UWS, and J. Boesenberg, BrownU) Well-formed granular, PO and BO chondrules (apparent diameter 1040±480 µm, N = 24; some glass-bearing) together with amoeboid, very fine grained CAI occur in a highly oxidized matrix (~30 vol.%, red-brown in thin section). Cr-bearing magnetite is present in chondrules. Accessory phases in the matrix include pentlandite, troilite and chromite; metal is absent.
