The sections consist of a few small chondrules (up to 0.8 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa0-36, orthopyroxene is Fs1-6. The matrix consists dominantly of an Fe-rich serpentine. Chondrules are flattened and exhibit a distinctive preferred alignment. The meteorite is a CM2 chondrite.
