Macroscopic Description - Kathleen McBride

074 has 50% rough brown/black fusion crust with polygonal fractures. 080 only has a small patch of black fusion crust. The interior of each meteorite has a black matrix with white and charcoal gray clasts and light colored chondrules. Minor weathering is visible.

Thin Section Description (,2) - Gretchen Benedix, Linda Welzenbach, Tim McCoy

The sections exhibit large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa_0-24 and pyroxenes from Fs_0-2. The meteorites are CV3 chondrites.
