Macroscopic Description - Cari Corrigan | |
95% black fusion crust on this flattened mass, black interior. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
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. Olivine compositions are Fa0-43. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered. The meteorite is a CM2 chondrite. |
