Macroscopic Description - Rachel Funk | |
Black fractured fusion crust on 35% of the exterior surface. The interior is a black matrix with 1 mm sized gray inclusions visible. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of a few small (up to 0.5 mm) chondrules, mineral grains and CAIs set in a black matrix. Rare metal and sulfide grains are present. Olivine compositions are Fa1-45, orthopyroxene is Fs2. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered. The meteorite is a CM2 chondrite. |
