The fusion crust on the exteriors of these carbonaceous chondrites range from brown to black to purplish patches and some have polygonal fractures. The interiors are a black soft matrix with mm sized white inclusions. |
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 Fa0-40, pyroxene is Fs1-6. The matrix consists pre-dominantly of an Fe-rich serpentine. The meteorites are CM2 chondrites. |
