Macroscopic Description - Cecilia Satterwhite

The exterior has brown fusion crust with oxidation and visible inclusions/chondrules.

Thin Section Description (,2) - Cari Corrigan, Tim McCoy

The section shows an aggregate of chondrules (up to 1 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Chondrules contain rare olivine. Weathering is modest, with moderate staining of some enstatite grains and minor alteration of metal and sulfides. Metal contains 2.2 wt. % SI. Microprobe analyses show the pyroxene is Fs_0-1. The meteorite is a type 3 enstatite chondrite, probably EH3.
