Original Classification EH3 Chondrite
Macroscopic Description - Cecilia Satterwhite
The exterior has a brown/black fusion crust with fractures penetrating the surface. Evaporites, chondrules/inclusions and rust are visible on the surface. The interior is a dark gray to black with abundant white inclusions. Some weathered areas are a brownish gray in color.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The section shows an aggregate of chondrules (up to 2 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Chondrules contain moderate to small abundances of olivine. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show the olivine is Fa1 and pyroxene is Fs1-4. Metal contains ~2.5 wt% Si. The meteorite is an EH3 chondrite.
