Macroscopic Description - Cecilia Satterwhite | |
Black/brown fusion is present over 60% of the exterior with oxidation and some large inclusions/chondrules visible. The dark gray to black matrix has abundant inclusions/chondrules that are lighter than the matrix. Some minor metal and oxidation is visible. | |
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer | |
The section exhibits numerous, well-defined chondrules (up to 3 mm) in a black matrix of fine-grained silicates, troilite and rare metal. Polysynthetically twinned pyroxene is abundant. The meteorite is moderately weathered. Weak shock effects are present. Silicates are unequilibrated; olivines range from Fa21-40, with most grains clustered at Fa17 or Fa30, and pyroxenes from Fs3-32. The meteorite is an LL3 chondrite (estimated subtype 3.6). |
