Macroscopic Description - Rachel Funk | |
The meteorite is 55% covered with black fusion crust. The exposed surface reveals the interior as 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 Fa5-44 and pyroxenes from Fs2-25. The meteorites are H3 chondrites (estimated subtype 3.5) and are likely paired |
