Thin Section Description (,2) - Cari Corrigan, Tim McCoy
This meteorite is dominated by fine-grained (~200 micron average grain size) basaltic material which occurs as both the host and clasts within this meteorite. Occasional coarser-grained clasts, with grain sizes up to 1 mm, are observed. Fine grained aphanitic clasts are also present. Mineral compositions are homogeneous with orthopyroxene (Fs60-63Wo3-6), with lamellae of augite (Fs30Wo41), and plagioclase (An84-92Or0.5-2). The Fe/Mn ratio of the pyroxene is ~31-34. The meteorite is a brecciated eucrite.
