Macroscopic Description: Kathleen McBride
The amount of fusion crust varies (from 25-70%) on these meteorites. All have dull purplish black fusion crust with polygonal fractures. The interior is a black matrix with mm-sized white clasts and a brittle texture.

The sections consist of a few small chondrules (up to 0.5 mm) that have been completely replaced by phyllosilicate set in an Fe-rich serpentine matrix. No isolated mineral grains or CAIs are apparent; rare sulfide grains are present. Unaltered olivine or pyroxene grains of sufficient size for microprobe analyses were not found. The meteorites are highly altered CM chondrites probably of petrologic type 1.
