Macroscopic Description - Kathleen McBride | |
90% of the exterior has dull brown/black fusion crust with oxidation halos. The rusty black matrix has a high metal content with a few rusty chondrules. This meteorite is hard. | |
Thin Section Description (,2) - Tim McCoy | |
Thin Section (,2) Description: Tim McCoy The section exhibits numerous small, well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Silicates are unequilibrated; olivines range from Fa8-35, with most grains Fa19-20, and pyroxenes from Fs8-19. The meteorite is an H3 chondrite (estimated subtype 3.8). |
