| Macroscopic Description - Mitchell Haller | |
| A patch of glossy black fusion crust covers 25% of the exterior. Areas without fusion crust have a greenish tint with large inclusions visible. The interior is a light to dark gray breccia with white inclusions and numerous clasts ranging in size from 1 mm to 1 cm. | |
| Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
| This meteorite is a breccia comprised of coarse- and fine-grained clasts up to 8 mm in maximum dimension, set in a comminuted matrix. The clasts are heavily shocked to impact melted. Pyroxenes range from Fs28Wo11 to Fs49Wo35 with a nearly continuous range of intermediate compositions. The Fe/Mn ratio of the pyroxene is ~60. Plagioclase is An80-98Or0-1. The meteorite is lunar. | |
