Petrography: The meteorite displays a dark greenish interior and is composed of well separated and sharply defined chondrules (apparent mean diameter about 600 μm) set into abundant matrix dominated by Fe-rich olivine, intermediate plagioclase, and Cr-rich magnetite. Minor phases include Ca-pyroxene and FeNi-sulfide; no metal was detected.

Geochemistry: Fe-rich matrix olivine: Fa31.1±0.3, FeO/MnO=107±9, n=11; unequilibrated olivine: Fa21.1±7.9 (Fa9.9-30.4, n=18); low-Ca pyroxene: Fs7.9±6.6Wo1.4±0.5 (Fs1.0-20.5Wo0.9-2.8, n=14); Ca-pyroxene: Fs1.2±0.1Wo42.3±0.6, n=5
