The section exhibits numerous well-defined chondrules (up to 2 mm) in a black matrix of fine-grained silicates, metal and troilite. Shock effects, including some flattening of chondrules, are evident. Polysynthetically twinned pyroxene is extremely abundant. The meteorite is weathered. Silicates are unequilibrated; olivines range from Fa9-26, with most grains Fa24-26, and pyroxenes from Fs3-4. The meteorite is an L3 chondrite (estimated subtype 3.7).
