Macroscopic Description: Kathleen McBride
90% of the exteriors are covered with a shiny, black fusion crust with a rough texture or regmaglypt. The interior matrices are crystalline in texture and tan to gray in color. Both contain small (<1 mm) white inclusions and black grains.

Thin Section (, 2) Description: Tim McCoy
These meteorites are so similar that a single description suffices. The meteorites are unbrecciated, medium-grained basalts composed of pyroxene (exsolved on a scale of 1-5µm), and plagioclase with minor metal and sulfide. The meteorite is extensively shocked, with mosaicism in both pyroxene and plagioclase. Mineral compositions are homogeneous with orthopyroxene (Fs55Wo4), with lamellae of augite (Fs28Wo36), and plagioclase (An88Or0.5). The Fe/Mn ratio of the pyroxene is ~30. The meteorites are unbrecciated eucrites.
