Macroscopic Description - Kathleen McBride | |
The exteriors are brown/black and have a rough, lumpy texture. The interiors are a fine grained black matrix with oxidation rinds. | |
Thin Section Description (,2) - Tim McCoy, Cari Corrigan, Linda Welzenbach | |
The sections 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. Extensive pre-terrestrial alteration is present in many of the chondrules, some of which are completely altered. Olivine compositions are Fa0-39. The matrix consists dominantly of an Fe-rich serpentine. The meteorites are CM2 chondrites. |
