Petrography: (D. Sheikh, FSU) Low chondrule abundance (700-1200 µm, n=3). Sample is composed of olivine, low-ca pyroxene, recrystallized plagioclase (average size 9±2 µm), troilite, Fe-Ni metal, Fe-oxides, and chromite. Geochemistry: Olivine (Fa18.8±0.5, n=13), Low-Ca Pyroxene (Fs16.6±0.6Wo1.2±0.1, n=12).
