# NASA data for MET 01076 Weathering: B Fracturing: B Pairing: MET 01076 Fa: 1-36 mol % Fs: 1-16 mol %
The exteriors have dull, rough, black fusion crust with pits and polygonal fractures. The interiors reveal a brown-black matrix with mm-sized clasts and chondrules. Colors range from white to tan.
The sections consist of many small chondrules with some up to 1.5 mm, mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa₀₋₅₃, orthopyroxene is Fs₁₋₁₆, although the majority of orthopyroxene is less than Fs₃. The matrix consists dominantly of serpentine. The meteorites are CM2 chondrites.
