Macroscopic Description: Kathleen McBride
The exterior of this meteorite is dark gray to black. Fusion crust covers ~80% of the surface area. Exposed interior is dark gray in color. The interior is dark, blackish-green crystalline texture. Some transparent, clear and light yellow crystals are present. It has a coarse grained texture with some dull rusty areas. Overall it has a dull metallic appearance. This achondrite is very coherent and difficult to break.

Thin Section (,7) Description: Tim McCoy
EET96042 - Cross-Polarized LightThe section consists of an aggregate of olivine grains up to 3 mm across. Individual grains are rimmed by moderately-weathered carbon-rich material containing traces of metal and troilite. Olivine grains exhibit undulatory extinction. Olivine grains have core compositions of Fa18, with rims reduced to Fa14. The meteorite is a ureilite.
