Macroscopic Description - Rachel Funk, Cecilia Satterwhite

The exteriors have 50-65% black, glassy fusion crust. The exposed surfaces show darker gray matrices with light gray and white inclusions and a slightly gray matrix with white and dark gray inclusions. The fresh surfaces reveal a gray matrix with darker gray and white inclusions. Minor amounts of rust are present.

Thin Section Description (,2) - Cari Corrigan, Tim McCoy

The sections are dominated by coarse grained basaltic material which is unbrecciated and heavily shocked. Mineral compositions are homogeneous with orthopyroxene (Fs₆₁Wo_2-5), augite (Fs₂₅Wo₄₄), and plagioclase (An_80-88Or_1-4). The Fe/Mn ratio of the pyroxene is ~33. The paired meteorites are coarse-grained, shocked, unbrecciated eucrites.
