Macroscopic Description - Cecilia Satterwhite | |
Black/brown fusion crust covers 90% of exterior with oxidation and rusty areas. The interior is a dark gray to black with some abundant light colored and weathered inclusions/chondrules. Some areas are very rusty. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section exhibits numerous large, well-defined chondrules (up to 2 mm) in a dark matrix of fine-grained silicates, metal and troilite. Minimal shock effects are present. Polysynthetically twinned pyroxene is present. Silicates are unequilibrated; olivines range from Fa1-27 and pyroxene is Fs9-15. The meteorite is an L3 chondrite (estimated subtype 3.6). |
