30% of the exterior surface has black patches of fusion crust and the exposed interior consists of dark, crystalline material. This crystalline interior has green subangular grains held together with rust, stained, elongated or radiating clear grains with some black or dark angular grains mixed in. The meteorite is slightly friable. |
This section shows an unusual texture of coarse crystals of pyroxene (up to 1.5 mm). Triple junctions are present though grains are not equigranular, suggesting that this meteorite has been recrystallized. Minor amounts of plagioclase and rare chromite are present. Orthopyroxene has a composition of Fs25Wo2-4 and plagioclase is An88-93Or0.3. The Fe/Mn ratio of the pyroxene is ~29. The meteorite is a diogenite. |
