Macroscopic Description: Kathleen McBride
This meteorite has a smooth black fusion crust which covers ~50% of the exterior surface area. The material underlying the fusion crust that is exposed reveals a greenish colored matrix and is very fine grained. It also contains very small white-cream colored inclusions. These inclusions are <1 mm in diameter. The interior of this achondrite is rather non-descript. It is black in color and very fine grained with very few inclusions that are < 1 mm in diameter.

Thin Section (,3) Description: Brian Mason
EET96001 - Cross-Polarized LightThe section shows a microbreccia of olivine clasts (up to 1.2 mm across) with a little plagioclase and polysynthetically twinned pyroxene in a black matrix. Traces of nickel-iron and troilite are present along grain boundaries. The meteorite appears to be unweathered. Microprobe analyses show olivine of variable compositions: Fa16-25,, mean Fa20. One grain of plagioclase, An36, was analyzed. The meteorite is classified as a ureilite.
