| Macroscopic Description - Cecilia Satterwhite | |
| 85% of the exterior has shiny black fusion crust, fractured in areas with large white inclusions visible. Some gray matrix is visible on exposed surface. The interior is a gray matrix with abundant light/dark inclusions of various sizes and a rusty vein runs through the interior. | |
| Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
| This section consists dominantly of coarse-grained pyroxene and plagioclase fragments and polymineralic igneous clasts with sizes up to 2 mm. A single coarse gabbroic clast approaching 1 cm in maximum dimension sits on one edge of the section, which contains laths of feldspar and equant pyroxenes with grain sizes up to 2 mm. Pyroxene compositions span the range from Fs17-63Wo1-44. This meteorite is a brecciated eucrite. | |
