80% of the exterior is brown/black fusion crust with fractures and evaporites; areas without fusion crust are dark brown with oxidation. The interior is a fine-grained black matrix with heavy oxidation in areas; light/weathered specks/inclusions are visible and some areas are rusty. |
The section consists 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 Fa1-46 and one pyroxene analysis was Fs1Wo3. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered. The meteorite is a CM2 chondrite. |
