95% of exterior is covered with a dark brown-black fusion crust that has light gray weathering along fracture lines and areas of very dark red rust. Exposed surfaces are light brown with dark red-orange rust spots. Fresh interior is dark brown matrix with round, light gray inclusions (up to 2 mm) and some areas of orange rust. |
The section consists of abundant chondrules (up to 2 mm in diameter) in a fine grained matrix of silicates, metal, and sulfide. Polysynthetically twinned pyroxene is abundant and some chondrules contain glassy mesostasis. The meteorite is moderately weathered and shocked. Olivine compositions range from Fa1 to Fa42 with an average of Fa14 and a standard deviation of 12. Pyroxenes are Fs1-8Wo0.5. The meteorite is likely an L3 chondrite of very low petrologic subtype, likely less than or equal to L3.2. |
