| Macroscopic Description - Kathleen McBride | |
| The exterior has no fusion crust. It has a black basaltic looking matrix with white to light gray clasts. There are a couple of areas where there is some off white material. The interior is the same as the exterior. | |
| Thin Section Description (,6) - Tim McCoy, Linda Welzenbach, Cari Corrigan, Rhiannon Mayne | |
| The section consists of a few large FeO-free enstatite grains (up to nearly 1 cm) set in a brecciated matrix that includes FeO-free diopsides up to ~200 microns. Shock-induced planar deformation features, mosaicism, and shock darkening are common as are shock melts in the matrix. Opaques include alabandite, troilite, metal, and an unidentified Cr-Ti sulfide, possibly brezinaite. The meteorite is an aubrite. | |
