Macroscopic Description - Cecilia Satterwhite | |
Black/brown fusion crust is present on 85% of the surface with visible chondrules and brown weathered areas. The dark gray to brown matrix has oxidation scattered throughout and abundant inclusions/chondrules of various colors and sizes 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 extremely abundant. The meteorite is moderately weathered. Silicates are unequilibrated; olivines range from Fa1-37 and pyroxenes from Fs12-19. The meteorite is an LL3 chondrite (estimated subtype 3.5). |
