Writeup from MB 102:
Northwest Africa 7039 (NWA 7039) (Northwest Africa) Purchased: 2012 Jan Classification: HED achondrite (Diogenite) History: Purchased by GHupé in 2012 February from a Moroccan dealer at the Tucson Gem and Mineral Show. Petrography: (A. Irving and S. Kuehner, UWS) Composed mainly of preferentially oriented tabular grains of orthopyroxene with minor olivine, clinopyroxene, anorthite, chromite, troilite and Ni-free metal. Orthopyroxene grains contain tiny inclusions of chromite (some bladed) oriented parallel to prominent cleavages. Geochemistry: Orthopyroxene (Fs25.3-25.4Wo2.9-2.3, FeO/MnO = 29-31), clinopyroxene (Fs8.9-9.2Wo45.4-44.4, FeO/MnO = 19-22), olivine (Fa29.7, FeO/MnO = 51). Classification: Diogenite. The foliated texture of tabular orthopyroxene grains is very unusual. | ||||||||||||||||||||||||||||
