A rough, black, fractured, pitted fusion crust with iridescent weathering halos covers about 85% of the exterior. Exposed areas are grey matrix with large (up to 1mm) rounded inclusions visible and has mostly been weathered to a dark brown. Fresh interior matrix is weathered to orange-brown with some darker inclusions visible. |
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 Fa6-23, with most grains Fa22, and pyroxenes from Fs3-24. The meteorite is an L3 chondrite (estimated subtype 3.8).
