This meteorite exhibits a granoblastic texture, with pyroxenes reaching 1.5 mm and plagioclase 1.0 mm, although most grains are smaller. Pyroxenes are exsolved on the scale of 1-20 microns, with orthopyroxene (Fs58Wo4), with lamellae of augite (Fs30Wo37), and plagioclase (An90Or0.2). The Fe/Mn ratio of the pyroxene is ~30. Staining by hydrated iron oxides is pervasive. The meteorite is an unbrecciated eucrite.
