Writeup from MB 103:

Northwest Africa 8595 (NWA 8595)

(Northwest Africa)

Purchased: 2014 Jan

Classification: HED achondrite (Howardite)

History: Purchased by F. Kuntz in January 2014 from a dealer in Rissani, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed of diogenite clasts and related debris, plus mineral debris derived from eucritic lithologies and rare basaltic eucrite clasts. Minerals include orthopyroxene, olivine (with several different compositions), exsolved pigeonite, calcic plagioclase, silica polymorph, chromite and troilite. One large (1.5 mm) forsteritic olivine grain was found.

Geochemistry: Diogenitic orthopyroxene (Fs24.0-25.2Wo3.0-2.0, FeO/MnO = 28-32, N = 3), orthopyroxene host (Fs43.0Wo2.2, FeO/MnO = 30), clinopyroxene exsolution lamella (Fs16.8Wo44.7, FeO/MnO = 27), augite (Fs30.6Wo40.7, FeO/MnO = 31), ferropigeonite (Fs78.9Wo14.1, FeO/MnO = 24), olivine (Fa73.0-86.6, FeO/MnO = 46-42; Fa11.3, FeO/MnO = 33).

Classification: Howardite.

Specimens: 16.14 g including one polished thick section at PSF; main mass with Kuntz.
