Northwest Africa

Purchased 2004 August

Achondrite (howardite)

A 68 g stone with fusion crust was purchased in Erfoud, Morocco. Description and classification (T. Bunch and J. Wittke, NAU): an unusual howardite that contains an array of plastically deformed shocked eucrite and diogenite clasts. Shock characteristics range from crushed cataclastics (S2-4), maskelynite-bearing (S4), recrystallized pyroxenes and plagioclase (S5) to melt clasts (S6) that contain olivine as the quenched mafic phase in place of typical pyroxenes. Diogenites: orthopyroxene, Fs25.0Wo2.9 (FeO/MnO = 29.4); plagioclase, An88.8; chromite, cr# = 76, mg# = 24. Eucrites:  orthopyroxene, Fs47.8-61.4Wo1.4-2.3 (FeO/MnO = 31.2-36); pigeonite, Fs51.3-56.8Wo7.7-12.6; augite, Fs27Wo28.1; plagioclase, An86.4-91.1. Quench olivine (<0.05 mm in diameter): cores, Fa17.9; rims, Fa36.4 (FeO/MnO = 41-47); low weathering grade. Specimens: type specimen, 13 g, NAU; main mass, GHupé.
