Thin Section (,6) Description - Tim McCoy, Linda Welzenbach, Cari Corrigan, and Rhiannon Mayne
This meteorite is dominated by fine-grained (~200 micron average grain size) basaltic clasts set in a clastic matrix. Mineral compositions are homogeneous with orthopyroxene (Fs62Wo2), with lamellae of augite (Fs27Wo43), and plagioclase (An88Or0.4). The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a brecciated eucrite.
