Notes:
# NASA data for LAP 10018 Weathering: A Fracturing: A/B Fa: 29-45 mol % Fs: 13-53 mol %
Shiny patches of brown/black fusion crust covers 60% of the exterior with some oxidation haloes and vugs. The interior is a gray matrix with no metal. Many angular multi-colored clasts of various sizes are visible.
The section shows a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with a few fine- to coarse-grained basaltic clasts ranging up to 5 mm and one large diogenitic clast approaching 1 cm. Olivines are Fa₂₉₋₄₅. Most of the pyroxene is orthopyroxene with compositions ranging from Fs₂₂₋₅₃Wo₂₋₁₁, a single augite of Fs₁₃Wo₃₉. Fe/Mn ratio is 21-36. The meteorite is a howardite.
