Macroscopic Description: Kathleen McBride
Mostly weathered fusion crust covers about 40% of the exterior surface of this meteorite. The crust resembles an overcooked brownie. The rest of the exposed surface is dark brown in color and looks like an amalgamation of melted brown chondrules. The interior of this carbonaceous chondrite is black and contains irregular shaped clasts and numerous white and rust colored chondrules 1-2 mm in size. The meteorite was easily broken and is very friable.

Plane-Polarized Light Cross-Polarized Light
The section exhibits well-defined, metal-rich chondrules up to 3 mm and metal spheres up to 1 mm in a dark matrix of FeO-rich phyllosilicate. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa1-32, with most Fa0-2, and pyroxenes from Fs1-4Wo0-1. The meteorite is probably a CR2 chondrite.
