Macroscopic Description: Kathleen McBride
Thin dark gray fusion crust covers 50% of this meteorite's exterior surface. Numerous vugs or plucked areas including a large one ~3 cm wide is on one surface. The interior matrix is gray and white crystalline matrix with some rusty stains. It is coarse grained, and has a soft friable texture.

Thin Section (, 5) Description: Tim McCoy
The section consists of a granoblastic matrix of pyroxene and plagioclase with coarser basaltic clasts up to 2.5 mm. Mineral compositions are relatively homogeneous with orthopyroxene (Fs₆₁Wo₂), with fine lamellae of augite (Fs₂₆Wo₄₄), and plagioclase (An_86-91Or_0-1). The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a brecciated eucrite.
