Macroscopic Description: Kathleen McBride

Thin, black shiny patches of fusion crust are present on this meteorite's exterior surface. Areas without fusion crust are weathered brown. The interior is brown and fine grained. A few mineral grains are visible and oxidation is present.

Thin Section (,2) Description: Brian Mason

The section shows plagioclase and pyroxene clasts, up to 1.5 mm across, in an opaque matrix of nickel-iron and troilite (the nickel-iron extensively weathered to brown limonite). Most of the pyroxene is hypersthene, with compositions clustered around Wo2Fs24, but a few calcium-rich grains were analyzed, up to Wo34Fs32. Plagioclase compositions are An91-96. Trace amounts of an SiO2 polymorph, probably tridymite, are present. The meteorite is a mesosiderite; it is very similar to QUE86900, with which it is probably paired.
