Macroscopic Description - Cecilia Satterwhite | |
50% of the exterior has black/brown fusion crust with rusty areas and oxidation. The interior is a weathered brown matrix with metal. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section exhibits small, well-defined chondrules (up to 1.5 mm) in a black matrix silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is rare. The meteorite is moderately weathered and moderately shocked. Silicates are unequilibrated; olivines range from Fa3-20 (with most Fa18), and pyroxenes are Fs16. The meteorite is an H3 chondrite (estimated subtype 3.7). |
