Macroscopic Description: Kathleen McBride
This achondrite has a dull black fusion crusted exterior with a few shiny glassy patches. There is moderate weathering on the exterior surface. The interior is steel gray in color with a crystalline texture. Some crystals are dark in color.

The sections consist of an aggregate of large olivine grains up to 1 mm across with numerous areas of finer-grained (~200m m), equigranular olivine, pigeonite and augite with abundant 120° triple junctions. Individual grains are rimmed by carbon-rich material containing traces of metal. Shock effects are numerous, including undulatory extinction, polysynthetic twinning and kink banding. Olivines have cores of Fa12-13, with rims reduced to Fa2. Pigeonite (Fs11Wo4) and augite (Fs7Wo29) are relatively homogeneous. These meteorites are paired ureilites and may be paired with EET96293.
