Petrography: The meteorite is dominantly composed of <1 mm sized olivine grains, sometimes poikilitically enclosing augite crystals. Olivine shows abundant reduced rims; the meteorite contains flaky graphite and Cr-bearing sulfides. Cracks are often found to be filled with barite likely due to intense terrestrial weathering. Geochemistry: Reduced rims in olivine: Fa1.4-4.5; olivine contains 0.28±0.03 wt% Cr2O3 and 0.22±0.02 wt% CaO; augite contains 1.58±0.03 wt% Cr2O3 and 3.37±0.03 wt% Al2O3 Classification: Ureilite, augite-bearing | ||||||||||||||||||||||||||||||||||||
