Found 2003

Achondrite (diogenite, polymict)

A 36 g partially crusted and complete stone was purchased in Erfoud, July 2003. Classification and mineralogy (J. Wittke and T. Bunch, NAU): plentiful, angular orthopyroxene clasts of considerable compositional range (Fs17.7-47.5Wo1.9-4.2) and a few large plagioclase clasts (An81–91.6) together with sparse cumulate and basaltic eucrite clasts. Clast modes: diogenite, 87 vol. %; eucrite, 9 vol. %; plagioclase clasts 2 % and shock clasts, 2 vol. %. Small metal inclusions (< 0.01 mm) in diogenite pyroxenes have very low Ni (0.15-0.37 wt%). Cumulate basaltic pyroxenes average Fs41.6Wo24.6. Overall mildly shocked; very little weathering. Specimens: type specimen 7.3 g, NAU; main mass, Boswell.
