The exterior is mostly brown with about 10% of black fusion crust. The interior is dark brown to black with some light colored crystalline faces in one area and some areas that are highly oxidized. |
The section consists of one portion which is an interlocking fabric of isolated pyroxene grains and basaltic clasts (up 1 mm) and a second portion dominated by a fine-grained comminuted matrix with isolated silicate grains up to 0.5 mm. Pyroxene (Fs14-58Wo1-41) includes low- to high-FeO (Fs14-58Wo1-4) orthopyroxene and low-FeO augite (Fs22-37Wo32-41). A single plagioclase grain is An91Or1. The meteorite is a howardite. |
