Writeup from MB 100:

Northwest Africa 6345 (NWA 6345)

(Northwest Africa)

Purchased: 2010 Jun

Classification: HED achondrite (Eucrite, polymict)

Petrography: (A. Irving and S. Kuehner, UWS): Polymict breccia composed mostly of basaltic eucrite clasts and debris, with sparse diogenitic clasts.

Geochemistry: Minerals include exsolved pigeonite (clinopyroxene lamellae within orthopyroxene host, and vice versa), diogenitic orthopyroxene, calcic plagioclase, silica polymorph, ilmenite and troilite. Exsolved pigeonite contains orthopyroxene (Fs53.9-64.4Wo2.3-1.9; FeO/MnO = 32.4-36.1) and clinopyroxene (Fs23.0-28.8Wo42.6; FeO/MnO = 30.6-31.7); diogenitic orthopyroxene is Fs26.5-26.6Wo3.7; FeO/MnO = 27.4-30.3).
