Macroscopic Description - Cecilia Satterwhite

The exterior has pitted brown/black fusion crust, with oxidation haloes and fractures. Areas without fusion crust have a pebbly texture and are brown/black in color. The interior is a rusty brown with heavy metal and a coarse grained texture.

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

The sections consist of an aggregate of large olivine and pyroxene grains up to 3.5 mm across. Individual olivine grains are rimmed by carbon-rich material containing traces of metal. Olivines have cores of Fa₂₄, with rims reduced to Fa₄. Pigeonite is Fs₁₉Wo₁₂. Subcalcic augite is Fs₁₃Wo₃₃. The meteorites are ureilites and are likely paired.
