Macroscopic Description - Cecilia Satterwhite

Most of the exterior is black/brown with some patches of fusion crust. The interior is a dark gray to black matrix with some oxidation and light/weathered inclusions/chondrules.

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

These sections exhibit large chondrules (up to 3 mm) and CAIs in a dark matrix. Fine-grained sulfides occur in the matrix. Olivines range from Fa_1-10. The meteorites are similar enough to be paired and are unequilibrated CV3 chondrites.
