The section exhibits numerous well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is abundant. The meteorite is moderately weathered. Silicates are unequilibrated; olivines range from Fa1-26, with most grains Fa20-26, and pyroxenes from Fs5-12. The meteorite is an L3 chondrite (estimated subtype 3.8).
