The section shows a groundmass of comminuted pyroxene (up to 1 mm) and plagioclase with fine- to coarse-grained basaltic clasts ranging up to 3 mm. It also contains clasts (up to 0.5 mm) of C1 carbonaceous chondrite material. Minerals include abundant orthopyroxene with compositions ranging from Fs23-55Wo2-4 (Fe/Mn ~30), a single augite of Fs30, plagioclase (An90-95) and SiO2. The meteorite is a howardite.
