A |
The fusion crust is slightly rough and black with iridescent weathering spots. The exposed interior appears light grey. The interior has a black matrix with dark, light, and rusty grey inclusions up to 2 mm. |
The section exhibits numerous small, 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 abundant. The meteorite is modestly weathered. Silicates are unequilibrated; olivines range from Fa5-44 and pyroxenes from Fs2-20. The meteorite is an H3 chondrite (estimated subtype 3.5). |
