Macroscopic Description - Cecilia Satterwhite

The exterior has 85% black/brown fusion crust with fractures and oxidation haloes. Some areas are rusty. The interior is a black matrix with white and weathered specks, minor oxidation throughout.

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

The section exhibits mm-sized, well-defined, metal rich chondrules and CAI’s in a dark matrix of phyllosilicate. Weathering is locally extensive. Silicates are unequilibrated; one olivine analysis was Fa₁, and pyroxenes formed two groupings at averages of Fs₁Wo_0.2 and Fs₁₂Wo₁. The meteorite is a CR2 chondrite.
