Macroscopic Description - Cecilia Satterwhite | |
The majority of the exterior is weathered brown with patches of black/brown fusion crust. The interior is brown with heavy oxidation and some darker matrix, metal is visible. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section exhibits a few poorly defined chondrules (up to 1.5 mm) in a black, shock-darkened matrix of fine-grained silicates, and coarse metal and troilite. Metal and sulfide exhibit fizz texture. The meteorite is moderately weathered. Olivine is Fa14, pyroxene is Fs12. The meteorite is a low FeO chondrite of type 5 (Russell et al. MAPS 1998). The meteorite is similar in mineral compositions to Willaroy and Suwahib (Buwah). |
