65% of the exterior is covered with black fusion crust and some minor evaporites. Fractures penetrate the surface. The exposed interior is gray with white and yellow inclusions (up to 3 mm in size). The interior is a gray matrix with dark gray, white and beige inclusions. |
The section shows a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with fine- to coarse-grained basaltic clasts ranging up to 3 mm. Most of the pyroxene is orthopyroxene with compositions ranging from Fs22-62Wo1-8 (most Fs20-30), with augite of Fs27-31Wo42. The meteorite is a howardite. |
