The section exhibits numerous large (up to 2 mm), well-defined chondrules 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 Fa9-31 and pyroxenes from Fs1-18. The meteorite is an L3 chondrite (estimated subtype 3.8).
