| Macroscopic Description - Kathleen McBride | |
| 85% of the meteorite is covered with brown/black fusion crust with shiny patches. The interior is a gray to tan matrix with white and dark gray inclusions and tan clasts. There are plucked areas and more weathering than 663 and 664. | |
| Thin Section Description (,4) - Tim McCoy, Linda Welzenbach | |
| The section shows a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with fine- to coarse-grained basaltic clasts ranging up to 3 mm. Large, mm-sized metal particles are relatively common in this section. Pyroxene includes diogenite-like compositions (Fs20-30Wo1-2) and eucrite-like compositions (Fs28-60Wo2-42). Plagioclase is An89-96. The meteorite is a howardite. | |
