Macroscopic Description - Cecilia Satterwhite | |
60% of the exterior is covered with black fusion crust. Frothy on one surface, areas without are dark gray to black. Interior is gray to black matrix with some 1-2 mm sized lighter grains visible; some oxidation. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists 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 Fa0-31 but most are under Fa2. Aqueous alteration of the matrix is substantial, but the chondrules are only moderately altered. The meteorite is a CM2 chondrite. |
