Macroscopic Description - Rachel Funk | |
50% of the exterior is covered with black fractured fusion crust. The exposed surface is black and fractured and minor evaporites are visible. The black matrix has white and gray chondrules/inclusions. | |
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 Fa1-36. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered. The meteorite is a CM2 chondrite. |
