Physical characteristics: Brownish to dark greenish rock partly covered with fusion crust.
Petrography: The meteorite displays a dark greenish interior and is largely composed of fine-grained recrystallized matrix dominated by Fe-rich olivine. Chondrules are only rarely encountered. Minor phases include intermediate plagioclase, low-Ca pyroxene, Ca-pyroxene and FeS. Cr-rich magnetite is abundant; metal was not detected.
Geochemistry: olivine: Fa28.9±0.2, FeO/MnO= 92±8, n=14; low-Ca pyroxene: Fs24.7±0.3Wo1.2±0.7, FeO/MnO= 62±5, n=13, Ca-pyroxene: Fs8.7±0.6Wo46.4±0.7, n=5; Cr2O3 in magnetite is about 2.7 wt%.
Note: The meteorite is sold without the scale cube.
