Original Classification H5 Chondrite (Anomalous)
Macroscopic Description - Cecilia Satterwhite
The exterior is covered by black fusion crust with rusty oxidized areas. Most of the interior is a rusty brown especially along fractures. Some dark gray areas are visible with metal and small light gray inclusions.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
This meteorite is a moderately metamorphosed, shock blackened chondrite whose mafic silicate compositions are more magnesian (Fa16, Fs14) than typically seen in H chondrites. It is similar to several chondrites described as low-FeO chondrites by Russell et al. (1998, MAPS, 853-856) and is petrologic type 5.
