Macroscopic Description - Rachel Funk | |
95% black fusion crust with red and orange rust halos covers the exterior surface. The interior is a black matrix with gray inclusions/chondrules. There are minor amounts of orange rust inside of the matrix. | |
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 Fa0-48 and pyroxenes from Fs16-24. The meteorite is an L3 chondrite (estimated subtype 3.5). |
