Black fractured fusion crust covers the exterior of this carbonaceous chondrite. It has a pebbly texture and fractures penetrate the surface, some inclusions/chondrules are visible as well as some oxidation. The interior is a black matrix with mm sized inclusions/chondrules of various sizes and colors. Some oxidation is heavy in areas and minor evaporites are visible. |
The sections both 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 with a peak at Fa1-2, pyroxene is Fs1-31. Aqueous alteration of the matrix is substantial. Meteorites are similar enough that one description suffices and are likely paired. The meteorites are CM2 chondrites. |
