Macroscopic Description - Mitchell Haller
Exterior has black patches of fusion crust. The rest of the exterior shows black matrix with white, black, and gray clasts. The exterior shows moderate fracturing and numerous clasts, the largest is 5.5 mm. Some minimal brown oxidation is visible on one exterior surface. The interior is has a black/gray matrix similar to the exterior but lighter. Black/gray/white inclusions and silvery metal faces are visible.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy
The section consists of coarsely comminuted pyroxene grains up to 0.7 mm with rare olivine present. Coarse pyroxene clasts are extensively shocked, with undulose extinction and shock darkening, and are set in a matrix of finely-comminuted grains. Pyroxenes and olivine are essentially FeO-free (Fs0; Fa0). The meteorite is an aubrite.
