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. |
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. |
MIL 05062 and MIL 05085 have high POEM (percentage of eucrite material) values, within the range of eucrites; MIL 05165, MIL 090640, and MIL 15428 have identical petrography to MIL 05062 and MIL 05085. Pairing: All five of these can be paired based on combination of terrestrial ages, find location, and petrographic textures. |
