Macroscopic Description - Kathleen McBride | |
50% of the exterior has brown/black fusion crust with oxidation haloes. The interior matrix is dark gray with 1-2 mm sized multicolored chondrules. | |
Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach | |
The section exhibits well-defined, metal-rich chondrules (100-300 microns) and a few CAIs in a dark matrix of FeO-rich phyllosilicate. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa1-31, with most Fa0-2, and pyroxenes from Fs3-6Wo0-1. The meteorite is probably a CR2 chondrite |
