Macroscopic Description - Cecilia Satterwhite | |
85% black fusion crust with oxidation covers the exterior. The interior is a dark gray to black matrix with oxidation and weathered inclusions/chondrules. | |
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. Olivine ranges in composition from Fa1-50. Two pyroxene analyses range from Fs1-2. Terrestrial weathering effects are modest. The meteorite is a CO3 chondrite. |
