A polished slice reveals numerous pale green olivine phenocrysts up to ~1 cm in diameter that poikilitically enclose smaller pyroxene grains. The groundmass consists of dark gray pyroxene grains up to 500 \u03bcm and smaller olivine grains.<\/p>\n<p class=\"MBNormal\"><strong>Petrography<\/strong>: (C. Agee, <i>UNM<\/i>) This meteorite has the approximate modal abundances: 50% clinopyroxene, 25% olivine, 10% maskelynite, with accessory ilmenite, chromite, Ti-Cr spinel, and pyrite. Clinopyroxene shows a tightly bound, continuous calcium enrichment trend. Olivine phenocrysts show a narrow compositional range from low Ca-pyroxene to pigeonite to subcalcic augite. Maskelynite is usually observed occupying pyroxene and olivine grain boundary pockets. Small vesicles are scattered throughout.<\/p>\n<p class=\"MBNormal\"><strong>Geochemistry<\/strong>: (M.
