The meteorite is a breccia of basaltic clasts, orthopyroxene grains, and coarse-grained orthopyroxenites in a comminuted matrix. Clasts reach up to 1 mm. Carbonaceous chondrite (presumably CM2) clasts up to 2 mm are present. Pyroxene compositions range over Fs19-65Wo2-44 (Fe/Mn~23-37). Plagioclase is An88-94Or1.
