About 99% of the exterior is covered with dark grey-brown possible fusion crust that is rough, fractured and pitted. Small exposed areas are a grey-brown matrix with small dark inclusions visible. Fresh interior is dark brown fine-grained matrix with large (up to 2 mm) round, light grey clasts along with orange rust spots in the matrix and clasts. |
The section exhibits numerous well-defined chondrules (up to 1 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 modestly weathered. Silicates are unequilibrated; olivines range from Fa3-31, and pyroxene is Fs7. The meteorite is an L3 chondrite (estimated subtype 3.6). |
