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). |
