Macroscopic Description - Mitchell Haller | |
Black fusion crust covers 60% of this ordinary chondrite’s exterior surface, some areas have yellow oxidation. The black matrix has some oxidation with abundant multicolored chondrules and inclusions. | |
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer | |
This section exhibits small (up to 1.5 mm), well-defined chondrules 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 Fa3-47 with a cluster at Fa22, and pyroxenes from Fs3-19. The meteorite is an LL3 chondrite (estimated subtype 3.2). |
