Northwest Africa 3148

Morocco

Purchased 2005 January

Achondrite (eucrite)

A single, 80% crusted stone (138 g) was purchased from a Moroccan dealer in Rissani by G. Hupé (Hupé) in 2005 January. Classification and mineralogy (A. Irving and S. Kuehner, UWS): Texturally, this specimen consists of groups of calcic plagioclase laths (An89.2-90.0Or0.4) interstitial to pyroxene grains.  The pyroxene-rich regions are mainly exsolved pigeonite, now consisting of orthopyroxene (Fs62.4-63.1Wo5.2-5.5, FeO/MnO = 27.6-30.3) and clinopyroxene (Fs30.1-30.5Wo42.6-42.7, FeO/MnO = 29.1-30.3), with associated discrete subcalcic augite and blebby fayalite inclusions.  Accessory phases are ilmenite, troilite, silica polymorph, kamacite and rare zircon.  Specimens: type specimen, 20.5 g, and one polished thin section, UWS; main mass, xHupé.
