(Northwest Africa)

Purchased: 2011 Jan

Classification: Carbonaceous chondrite (CK6)

Petrography: (A. Irving and S. Kuehner, UWS) Very sparse recrystallized chondrules (some with magnetite-rich rims) in a recrystallized matrix. Olivine, clinopyroxene, intermediate plagioclase, Cr-bearing magnetite and pentlandite. Fa contents and Fs contents in clinopyroxene are mutually consistent with this being an equilibrated chondrite.
