These meteorites are so similar that a single description suffices. The sections show a groundmass of comminuted pyroxene and plagioclase (up to 2.5 mm) with fine- to coarse-grained basaltic and pyroxenitic clasts ranging up to 2 mm. Both contain clasts similar in texture to the unusual eucrite ALHA81001. Pyroxenes include orthopyroxene (Fs17-31Wo0-4) and finely-exsolved pyroxenes that include augite (Fs28Wo37) and orthopyroxene. The Fe/Mn ratio of pyroxene is ~30. Plagioclase is An70-95Or0-2. The meteorites are howardites.
