Macroscopic Description - Cecilia Satterwhite
The exterior has 95% black/brown fusion crust with rusty areas. The interior is a rusty brown with metal and has a crystalline texture.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy and Linda Welzenbach
The meteorite is an equigranular aggregate (1 mm grain size) of olivine and pyroxene and very rare plagioclase in a metal-rich matrix. Stringers of metal and rare sulfide occupy grain boundaries between mafic silicates. Olivine (Fa12), low-Ca pyroxene (Fs10Wo5), high-Ca pyroxene (Fs6Wo37). The meteorite is a lodranite.
