Thin Section (,2) Description - Corrigan, Linda Welzenbach, Andrew Beck and Nicole Lunning
This meteorite is dominated by fine-grained (~200 micron average grain size) basaltic material which occurs as both the host and clasts. Occasional coarser-grained clasts, with grain sizes up to 0.5 mm, are observed. Mineral compositions are homogeneous with orthopyroxene (Fs62Wo2), with lamellae of augite (Fs27Wo43), and plagioclase (An91Or0.3). The Fe/Mn ratio of the pyroxene is 27-32. The meteorite is a brecciated eucrite.
