Macroscopic Description - Cecilia Satterwhite
The exterior has black/brown fusion crust with oxidation and minor evaporites. The dark gray to black matrix has abundant inclusions and chondrules of various sizes and colors. Some rusty oxidation is scattered throughout.
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer
The section exhibits numerous, large, well-defined chondrules (up to 1 cm) in a black matrix of fine-grained silicates, troilite and rare metal. This meteorite is brecciated. Polysynthetically twinned pyroxene is abundant. The meteorite is mildly weathered. Weak shock effects are present. Silicates are unequilibrated; olivines range from Fa18-38, with most grains clustered at Fa18 or Fa30, and pyroxenes from Fs3. The meteorite is an L3 chondrite (estimated subtype 3.6).
