Macroscopic Description: Cecilia Satterwhite
The exterior has a black fusion crust over 60% of its surface. The fusion crust is frothy in areas and fractures are visible. Evaporite deposits and rust are present. Areas without fusion crust are rusty brown with some rust stained inclusions. The interior is a dark gray matrix with abundant inclusions. Inclusions are lighter in color than the surrounding matrix and some are weathered.
Thin Section (,2) Description: Valerie Reynolds and Tim McCoy
The section exhibits numerous well-defined chondrules (up to 2 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 Fa0-26 and pyroxenes from Fs7-17. The meteorite is an L3 chondrite and may be of low subtype (estimated subtype 3.3).
