Writeup from MB 105:
Northwest Africa 10079 (NWA 10079) (Northwest Africa) Purchased: 2014 Oct Classification: HED achondrite (Diogenite, polymict) History: Purchased by Fabien Kuntz in October 2014 from a Moroccan dealer at the Munich Show. Petrography: (A. Irving and S. Kuehner, UWS) Fresh fragmental breccia composed of angular clasts of mostly orthopyroxene (of several different compositions) with accessory anorthite, Al-poor chromite, silica polymorph, olivine, kamacite, Al-rich chromite, ilmenite and troilite, plus several percent of lithic clasts of basaltic and cumulate eucrite. Geochemistry: Olivine (Fa33.0-39.5, FeO/MnO = 53-55, N = 2), orthopyroxene (Fs20.9Wo0.5; Fs26.0Wo1.8; FeO/MnO = 29-36; N = 2), clinopyroxene host (Fs29.2-30.1Wo41.2-40.5, FeO/MnO = 32-36, N = 2), low-Ca pyroxene exsolution lamella (Fs34.3Wo4.2, FeO/MnO = 28).. Classification: Diogenite (polymict breccia). The range in Fs content (>5 mol. %) for analyzed orthopyroxenes in this breccia is much greater than in any intact diogenite or monomict diogenite breccia, and the presence of eucritic clasts establishes that it is polymict. Specimens: 21.78 g including one polished thin section at PSF; main mass with. Kuntz. | ||||||||||||||||||||||||||||||
