Thin Section Description (,2) - Cari Corrigan, Tim McCoy, Linda Welzenbach | |
This meteorite is dominated by fine-grained (~200 micron average grain size) basaltic material which occurs as both the host and clasts. Mineral compositions are homogeneous with orthopyroxene (Fs63Wo2), with lamellae of augite (Fs28Wo43), and plagioclase (An85Or1). The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a monomict, brecciated eucrite. |
