Writeup from MB 103:

Northwest Africa 8354 (NWA 8354)

(Northwest Africa)

Purchased: 2013

Classification: HED achondrite (Diogenite, polymict)

History: Purchased by Stefan Ralew from a Moroccan dealer in 2013.

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed predominantly of clasts of a feldspathic diogenite lithology accompanied by mineral debris derived from several eucritic lithologies. Feldspathic diogenite clasts are composed of orthopyroxene with ~5 vol.% calcic plagioclase, silica polymorph, chromite, Ti-chromite, troilite and Ni-free metal.

Geochemistry: Diogenitic orthopyroxene (Fs30.8Wo5.4, FeO/MnO = 28), orthopyroxene (Fs48.3Wo3.2, FeO/MnO = 34), pigeonite (Fs43.1Wo8.8, FeO/MnO = 32), augite (Fs22.4Wo40.4, FeO/MnO = 28).

Classification: Diogenite, feldspathic, polymict breccia.

Specimens: 11.4 g including one polished thin section at UWB. The remaining material is held by Ralew.
