Northwest Africa 11235 (NWA 11235)

(Northwest Africa)

Purchased: 2016 Jun

Classification: HED achondrite (Diogenite)

History: Purchased by Fabien Kuntz in June 2016 from a Moroccan dealer at the Ensisheim Show.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia consisting of angular mineral grains of predominantly orthopyroxene with subordinate olivine, anorthite and accessory silica polymorph, merrillite, chromite and troilite in a sparse matrix. Grains of both orthopyroxene and olivine exhibit more ferroan rims.

Geochemistry: Low-Ca pyroxene (core Fs24.0Wo2.3, FeO/MnO = 35, N = 1; rim Fs32.2Wo6.6, FeO/MnO = 28, N = 1), olivine (core Fa33.2, FeO/MnO = 45, N = 1; rim Fa 35.0, FeO/MnO = 48, N = 1), plagioclase (An93.0-93.6Or1.6-1.7, N = 2).

Classification: Diogenite breccia.

Specimens: 4.74 g including one polished thin section at PSF; remainder with Kuntz.
