50% of the exterior of this meteorite is covered with black fusion crust with shiny patches. The exposed interior shows gray matrix. The interior matrix is a gray, crystalline with white inclusions <1 mm in size. There are a few small areas with a slight rust color and black veins.
The section shows a groundmass of coarse (up to 2 mm) comminuted pyroxene, with minor plagioclase and olivine. Orthopyroxene has a composition of Fs₂₆Wo₂; plagioclase is An₈₈Or0.5; olivine is Fa₃₀. The Fe/Mn ratio of the pyroxene is ~28. The meteorite is a diogenite.
