Writeup from AMN 29(1):
Macroscopic Description: Kathleen McBride The exteriors of these ordinary chondrites have dull, black weathered fusion crust with polygonal fractures. The interiors are a dark matrix stained with rust. Numerous chondrules and a few irregularly shaped clasts are visible. Metal is also present. Thin Section (,2) Description: Tim McCoy and Linda Welzenbach The meteorites are so similar that a single description suffices. The sections exhibit numerous well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa1-29 and pyroxenes from Fs3-29. The meteorites are L3 chondrites (estimated subtype 3.6).
