Macroscopic Description: Cecilia Satterwhite
The exterior of this achondrite has about 20% of black fusion crust, frothy on some
surfaces, and some fractures are visible. The rest of the exterior is dark gray with abundant white inclusions. The interior is a lighter gray with abundant white clasts. Some darker minerals are visible and minor weathering. Some clasts are as large as 1.5 cm across.
Thin Section (, 6) Description: Tim McCoy
The section consists of coarse (up to 2.2 mm) pyroxene and plagioclase grains and coarse-grained basalt clasts, which reach 2.5 mm in diameter. Orthopyroxene (Fs60Wo2-5) contains lamellae of augite (Fs28Wo44) and plagioclase is An88Or0.6. Shock effects include mosaicism and planar fractures in pyroxene. The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a brecciated eucrite.
