The section exhibits numerous small, well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Silicates are unequilibrated; olivines range from Fa1-21, with a weak peak at Fa19, and pyroxenes from Fs2-9. The meteorite is a H3 chondrite (estimated subtype 3.6).
