| Macroscopic Description - Kathleen McBride, 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 Description (,2) - Cari Corrigan, Tim McCoy, 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). | |
