A broken surface reveals fine-grained, light gray-green basaltic texture. Petrography: (C. Agee, UNM) Microprobe examination of a polished epoxy mount shows ~10% olivine, ~60% pyroxene, ~25% maskelynite, ubiquitous Cr-Ti-Fe oxides and troilite. Pyroxenes and olivines show igneous zonation in BSE images. Heavily shocked, with grain size from ~50-500 μm. Geochemistry: (C. Agee and N. Muttik, UNM) EMPA. Olivine Fa49.9±4.9, Fe/Mn=55±1, n=24; pigeonite Fs31.8±4.6Wo10.1±2.2, Fe/Mn=31±2, n=36; augite Fs24.0±2.6Wo29.4±5.0, Fe/Mn=29±2, n=7; maskelynite Or3.1±0.5Ab48.5±3.0An48.3±3.4, n=12.
