Writeup from MB 88:

Northwest Africa 1819

Morocco

Purchased 2003 January

Achondrite (Howardite)

Four broken, partly crusted stones (total 68.4 g) were purchased in Rissani by a Moroccan dealer for N. Oakes (Oakes) in 2003 January.  Classification and mineralogy (A. Irving and S. Kuehner, UWS): Breccia consisting mainly of cumulate eucrite debris with subordinate fragments of pinkish orthopyroxene and sparse basaltic eucrite clasts.  The proportion of diogenitic orthopyroxene fragments (Fs1.5Wo24.2, FeO/MnO = 24.2) exceeds the 10 vol.% necessary to classify this sample as a howardite.  The cumulate eucrite debris consists of mineral and polycrystalline clasts composed of pigeonite, anorthite, silica polymorph, troilite, ilmenite and rare fayalite.  Specimens: type specimen, 14 g and one polished thin section, UWS; main mass, Oakes.
