Macroscopic Description - Mitchell Haller | |
Black fusion crust covers 60% of the exterior, some areas are porous. The top has a moss-like texture, while the bottom is smooth and porous. Areas without fusion crust show a dark gray matrix. Some fractures penetrate the surface. The interior is a dark gray matrix with shiny metal and small brown spots, 1-2 mm rusty and weathered. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of rare chondrules, large sulfides (up to 0.3 mm) and magnetite. The meteorite is little weathered, but extensively shock blackened. Silicates are homogeneous. Olivine is Fa34-38. The meteorite appears to be a CK5 chondrite, although the silicates are slightly richer in FeO than typical for CK chondrites (Fa29-33). |
