Macroscopic Description - Cecilia Satterwhite | |
Exterior surface has 90% black/brown fusion crust with oxidation halos and rust. The interior is medium gray matrix with heavy oxidation in areas. Abundant mm sized inclusions/chondrules and metal are present. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section exhibits numerous small (up to 1.5 mm), well-defined chondrules in a black matrix of fine-grained silicates, metal and troilite. Polysynthetically twinned pyroxene is abundant. The meteorite is moderately weathered. Silicates are unequilibrated; olivines range from Fa18-27 and pyroxenes from Fs6-28. The meteorite is an L3 chondrite (estimated subtype 3.8). |
