Macroscopic Description: Cecilia Satterwhite
The exterior of this irregular-shaped meteorite is dark brown to black and shiny. The interior has an orangish-brown color with abundant silicates in metal. Surfaces are rough and jagged. The white deposit present is probably a weathering feature.
Thin Section (,5) Description: Brian Mason
The section consists of silicate clasts, up to 9 mm in maximum dimension, and individual silicate grains, in a nickel-iron matrix. The clasts are made up mainly of anhedral pyroxene and olivine grains, with some plagioclase. Microprobe analyses show the following compositions: olivine, Fa5; orthopyroxene, Wo2Fs7; diopside, Wo45Fs3; plagioclase, An12. The meteorite is an iron with silicate inclusions.
