The exterior has a shiny black patch of fusion crust. The interior is a gray matrix with some light and dark inclusions. Some oxidation and minor evaporites are visible. |
The section shows a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with diogenite and cumulate eucrite clasts ranging up to 3 mm. Most of the pyroxene is orthopyroxene with compositions ranging from Fs23-60Wo2-41 (most Wo2-10). This meteorite is a howardite. |
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. |
