The exteriors of these paired carbonaceous chondrites have varying amounts of fusion crust (40%-90%) and the colors range from purplish black to brown. The interiors are generally black with some oxidation, most have a powdery texture and contain chondrules of various colors. Varying degrees of oxidation exist in all these meteorites. |
The meteorites are likely paired and a common description suffices. 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 Fa1-61, orthopyroxene is Fs1-42. The meteorites are CM2 chondrites. |
