Macroscopic Description - Rachel Funk, Cecilia Satterwhite

The exteriors of these meteorites are covered with black/brown fusion crust; some rust is visible. The exposed surfaces reveal the interiors are a black matrix with gray, beige and white chondrules that are up to 3 mm in size

Thin Section Description (,2) - Cari Corrigan, Tim McCoy

The sections exhibit 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 extremely abundant. The meteorites are highly weathered. Silicates are unequilibrated; olivines range from Fa_5-44 and pyroxenes from Fs_2-25. The meteorites are H3 chondrites (estimated subtype 3.5) and are likely paired
