Macroscopic Description: Kathleen McBride
The exteriors of these meteorites are covered with a rough, black fusion with polygonal fractures. The interior reveals a medium to dark gray matrix with white, irregularly shaped inclusions. A few dark crystalline clasts are present. Chrondrules are mm sized and are gray or rust in color.

The sections are so similar that a single description suffices. The sections exhibit large chondrules (up to 3 mm) and CAIs in a dark matrix with minor metal and sulfide. Olivines range from Fa0-45, with many Fa0-5, and pyroxenes from Fs0-2. The meteorites are CV3 chondrites.
