Macroscopic Description - Cecilia Satterwhite | |
Fractured black fusion crust with some oxidation covers the exterior surface. The interior is black with some oxidation. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. The section consists of two regions, one of which contains more abundant metal suggesting the meteorite may be a breccia. Olivine ranges in composition from Fa1-45. Two pyroxene analyses range from Fs1-30. Terrestrial weathering effects are modest. The meteorite is a CO3 chondrite. |
