Macroscopic Description: Kathleen McBride
60% of the exterior is covered with black "wrinkled" appearing fusion crust. The areas without fusion crust are a black crystalline material with vugs. The binocular microscopic view of the exterior surface appears melted or fused together. The interior reveals a coarse grained, dark green to blackish crystalline matrix with a granular texture. This nakhlite is unbrecciated and homogeneous with interlocking grains and minor rust.

The section is dominated by lathy to equant clinopyroxene that reaches 2 mm in maximum dimension. Mesostasis occupies approximately 20% of the rock and contains skeletal iron-titanium oxides. Clinopyroxenes have core compositions of Fs21 Wo40 with rims reaching Fs49 Wo34. Olivine was not observed. The meteorite is a nakhlite. Its pyroxenes are compositionally similar to Lafayette, but it is richer in mesostasis and unusual for nakhlites in lacking olivine.
