Macroscopic Description - Cecilia Satterwhite

40% of the exterior has black, frothy, fractured and pitted fusion crust. The areas without fusion crust are brown and heavily fractured/pitted with rusty areas. Some weathered inclusions/chondrules and minor evaporites are visible. The interior is a black matrix with an evaporite rim on one surface, and some oxidation in areas. Some mm-sized weathered and white inclusions are visible.

Thin Section Description (,2) - Cari Corrigan, Tim McCoy

The section consists 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 Fa_0-39. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered. The meteorite is a CM2 chondrite.
