Northwest Africa

Found 2003

Achondrite (howardite)

Three stones that weigh a total of 2.45 Kg were purchased in Erfoud, Morocco in December 2003. Description and classification (J. Wittke and T. Bunch, NAU): howardite breccia of fine-to medium clast size (<3.0 mm); very heterogeneous distribution of diogenite clasts; cumulate basalt clasts were probably derived from the same basaltic provenance. All clasts are highly shocked (shock level 3-6): pyroxenes and plagioclase were subjected to shock-induced, solid-state recrystallization; a few have completely melted. Eucrite pigeonite, Fs47.3-52Wo16.7-7.7; Ca-rich pyroxene, Fs40Wo25.2, Fe/Mn = 28.5; plagioclase, An90.7-92.0; chromite, cr# = 80.3, fe# = 94.8; metal, Ni = 1.99 wt. %; ilmenite and silica. Diogenite orthopyroxene, Fs48.4-54.9Wo1.1-2.7, Fe/Mn = 32.5. Possibly paired with NWA 1929. Low weathering grade. Specimens: 3.8 g, NAU; 21.4 g, UCLA; main mass, Hupé.
