95% of the exterior is covered with black, shiny fusion crust with bubbles. The interior matrix is white, fine grained and is moderately friable. The inclusions are tan, black, and greenish in color. |
The section exhibits a range of grain sizes, although boundaries between these regions are diffuse. The meteorite is heavily-shocked, commonly exhibiting mosaicism. Mineral compositions are homogeneous with orthopyroxene (Fs63Wo2), with lamellae of augite (Fs27Wo43) and plagioclase (An85-89Or0.5). The Fe/Mn ratio of the pyroxene is ~28. The meteorite is a eucrite. |
