| Macroscopic Description - Cecilia Satterwhite | |
| Patches of black/brown fusion crust are on the weathered brown exterior. The dark gray to black matrix has abundant inclusions/chondrules of various colors and sizes. Some areas are weathered brown with rust. This meteorite was difficult to break. | |
| Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Tim McCoy | |
| The section exhibits large (up to 3 mm), poorly-defined chondrules and CAIs in a dark matrix of mafics and FeO-rich phyllosilicate. Metal is found disseminated throughout, along with abundant sulfides, though very few metal rimmed chondrules are seen. Polysynthetically twinned pyroxene is abundant. Olivines range from Fa3-7 and pyroxenes from Fs1-3Wo1-4. The section is heavily weathered. The meteorite is probably a CR2 chondrite, although the extent of aqueous alteration appears to be less than is typical for CR2 chondrites. | |
