A/B |
A very dark brown/black fusion crust with fractures and iridescent weathering halos covers about 80% of the exterior of the rock. The exposed areas show some grey/brown matrix that is mostly covered with dark red/brown rust. Interior matrix is very dark brown with some areas of grey matrix visible. There are grey and light brown round inclusions up to 2 mm in size, orange rust and metal throughout. |
The section exhibits numerous well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is common. The meteorite is moderately weathered. Silicates are unequilibrated; olivines range in composition from Fa19-27, and pyroxene from Fs9-48. The meteorite is an L3 chondrite (estimated subtype 3.6). |
