| Macroscopic Description - Kathleen McBride | |
| The exterior has brown fusion crust with polygonal fractures and oxidation haloes. The interior is a rusty crystalline matrix which is moderately friable. This mesosiderite has a B/C fracturing and a C weathering. | |
| Thin Section Description (,2) - Tim McCoy, Cari Corrigan, Nicole Lunning | |
| This meteorite is dominated by orthopyroxene and plagioclase grains with grain size approaching 2 mm. Most grains are equant with ~0.5 mm rounded to elongate metal phosphide particles, with less abundant and heavily weathered troilite. Pyroxene compositions are Fs36Wo3, feldspars are An95Or0.1. This meteorite may be a metamorphosed clast from a mesosiderite. | |
