| 5-10% of the exteriors have a purplish black fusion crust with rough areas and a slight sheen. The interiors reveal a black charcoal-like, platy matrix, with tiny white and tan inclusions. |
| The sections consist of a few small chondrules (up to 1 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa0-43, with a peak at Fa0-2, orthopyroxene is Fs0-5. The matrix consists dominantly of an Fe-rich serpentine; chondrules are relatively unaltered. The meteorites are CM2 chondrites and probably paired. |
