Black polygonally fractured fusion crust is on the exterior of these meteorites. The interior of these carbonaceous chondrites is a black powdery matrix with light gray and white chondrules and 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 Fa1-48; rare orthopyroxenes are Fs1-38. The matrix consists pre-dominantly of an Fe-rich serpentine. The meteorites are CM2 chondrites. |
