Original Classification LL3.8 Chondrite
Macroscopic Description - Kathleen McBride and Cecilia Satterwhite
The exteriors have brown/black fusion crust with oxidation haloes and chondrules/inclusions visible. Areas without fusion crust are a rusty orange brown. The interiors are rusty black with abundant white/gray/weathered inclusions/chondrules and metal.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The sections exhibit numerous large, well-defined chondrules (up to 1.5 mm) and occasional melt clasts in a matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa11-33 and pyroxenes from Fs6-34. The meteorites are LL3 chondrites (estimated subtype 3.8).
