Macroscopic Description - Kathleen McBride | |
Only small patches of black fusion crust are present on the surface of this meteorite. The rest of the exterior is a rusty brown color. The interior is rusty with small black patches of matrix and it has a sugary texture. Some gray colored chondrules are visible. | |
Thin Section Description (,2) - Tim McCoy | |
The section exhibits numerous well-defined chondrules (up to 1 mm), metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is abundant. Weathering is pervasive, with extensive staining. Silicates are unequilibrated; olivines range from Fa4-22 and pyroxenes from Fs13-16. The meteorite is probably an L chondrite of subtype ~3.6. |
