This meteorite is dominated by orthopyroxene, clinopyroxene and plagioclase grains in a matrix of approximately 30% metal. Minor sulfide and chromite grains are present with sulfide often occurring as dispersed, small grains surrounding larger metal grains. Grain sizes are up to 1 mm. Pyroxenes are zoned orthopyroxene, Fs28-57Wo2-11, and exsolved clinopyroxene with augite Fs25-27Wo42-45. Feldspars are An88-91. This small meteorite is probably a metal rich clast from a mesosiderite, although metal rich eucrites are known.
