Macroscopic Description: Kathleen McBride
The exterior has thick dull black fusion crust. The matrix is a rusty black with moderate amounts of metal. Light and rusty chondrules are visible.


Thin Section (,2) Description: Valerie Reynolds and Tim McCoy
The section exhibits numerous well-defined chondrules (up to 2.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Polysynthetically twinned pyroxene is abundant and a few chondrules contain glass. The meteorite is moderately weathered. Silicates are unequilibrated; olivines range from Fa5-40 and pyroxenes from Fs4-16. The meteorite is an L3 chondrite and may be of low subtype (estimated subtype 3.3).
