Macroscopic Description - Cecilia Satterwhite | |
Brown/black fusion crust with oxidation halos and fractures cover the exterior of this ordinary chondrite. The exterior has some pitted areas and exposed gray matrix. The interior is a gray matrix with heavy oxidation. Some large and small light/dark/weathered inclusions/chondrules and minor metal are 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. Weak shock effects are present. Polysynthetically twinned pyroxene is present. The meteorite is moderately weathered and moderately shocked. Silicates are unequilibrated; olivines range from Fa10-37, and pyroxenes from Fs23-25. The meteorite is an L3 chondrite (estimated subtype 3.5). |
