Official Meteoritical Bulletin entry for Northwest Africa 3160:
Northwest Africa 3160 Morocco Find: July 2005 Achondrite (lunar, mare basalt breccia)
History: In July 2005, A. and G. Hupé purchased three broken stones with a total weight of 34 g from a Moroccan dealer in Erfoud, Morocco. Physical Characteristics: The largest stone (28 g) has a partial thin weathered fusion crust. Petrography: (R. Zeigler and R. Korotev, WUSL; A. Irving and S. Kuehner, UWS) The large specimen consists almost entirely of a fine-grained, olivine-phyric basalt clast with minor attached breccia matrix and appears to be part of a larger, coarse-grained, polygenic breccia. The two small stones are pieces of the breccia. The basalt contains phenocrysts of euhedral to subhedral olivine (~0.1–0.9 mm) and minor chromite (<0.1 mm). Geochemistry: Olivine phenocrysts are zoned, with cores typically Fo55–70 and rims extending to ~Fo40 with FeO/MnO ratios of 91–105. The groundmass has spinifex olivine (Fo29) and skeletal pyroxene (En37–39Wo11–13; FeO/MnO = 71–75) set in a fine-grained matrix of pyroxene (En35–39Wo20–23), olivine (~Fo22), and glass. The breccia lithology is a fragmental breccia consisting primarily of olivine (Fo6–82) and pyroxene (En1–68Wo9–39Fs16–83), with minor amounts of plagioclase (An82–97) and trace silica; hedenbergite-fayalite-silica symplectite (after former pyroxferroite), and Fe-Ti-Cr oxides. Classification: Achondrite (lunar, mare basalt breccia). Specimens: A 4.8 g type specimen and one polished thin section are on deposit at UWS. A 2.1 g specimen is on deposit at WUSL. AHupé holds the main mass.
