Macroscopic Description - Cecilia Satterwhite | |
The exterior is gray with patches of black fractured fusion crust. It is frothy in areas with evaporites and fractures that penetrate the surface. The black matrix has white specks/inclusions and some oxidation is visible. Some evaporites are visible on interior. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of small (up to 0.5 mm) completely altered and elongate chondrules set in an altered matrix that is highly fractured. Fractures are aligned in the direction of chondrule elongation. Rare sulfide grains are present. No unaltered mafic silicates remain. A few rare calcite grains were encountered. The meteorite is a CM1 chondrite. |
