Macroscopic Description: Kathleen McBride
The amount of fusion crust on these meteorites ranges from 30 to 60%. All have purplish fusion crust with polygonal fractures and rust on some surfaces. Interiors reveal a black, platy matrix with 1 mm-sized white inclusions. These meteorites are friable.

Thin Section (, 2) Description: Gretchen Benedix, Linda Welzenbach and Tim McCoy
The sections consist of a few small chondrules (up to 0.5 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa0-61,with the majority of olivine falling around Fa1; orthopyroxene is Fs1-4. MET 01072 and 01078 exhibit foliated texture with somewhat flattened chondrules. The matrix consists dominantly of an Fe-rich serpentine. The meteorites are CM2 chondrites.
