Thin Section Description (,2) - Cari Corrigan, Tim McCoy
The section represents a single, coarse-grained, cataclastized, brecciated, cumulate eucrite. The section is composed of coarse (up to 2 mm) pyroxene and plagioclase, crosscut by numerous offset fractures. Mineral compositions are homogeneous with orthopyroxene (Fs63-66Wo2), with lamellae of augite (Fs20-29Wo52-66), and plagioclase (An88-92Or0.5). The Fe/Mn ratio of the pyroxene is ~31. The meteorite is a polymict eucrite.
