Macroscopic Description - Cecilia Satterwhite

The exterior has black fusion crust with some exposed gray matrix, inclusions/chondrules are visible. Most of the interior is brown with metal and abundant inclusions/chondrules of various sizes and color; some dark gray matrix is visible.

Thin Section Description (,2) - Cari Corrigan, Tim McCoy

The section exhibits numerous large, well-defined chondrules (up to 2 mm) in a black matrix of fine-grained silicates, metal and troilite. Polysynthetically twinned pyroxene is present. Weak shock effects are present. Weathering in the meteorite is minor. Silicates are unequilibrated; olivines range from Fa_10-25, and pyroxenes from Fs_15-19. The meteorite is an L3 chondrite (estimated subtype 3.5).
