Writeup from MB 100:

Northwest Africa 6707 (NWA 6707)

(Northwest Africa)

Purchased: Mar 2011

Classification: HED achondrite (Eucrite)

Petrography: Fresh breccia composed mostly of clasts and related debris of cumulate eucrite lithologies, with minor diogenitic orthopyroxene grains and clasts of fine-grained basaltic eucrites. Most of the very calcic plagioclase is maskelynite, with a few percent being spherulitic and birefringent (produced by quenching of shock-melted plagioclase). Other minerals are exsolved pigeonite and accessory Ti-chromite, taenite (some associated with martensite, troilite and chromite) and rare Na-K-bearing plagioclase.

Geochemistry: Clinopyroxene exsolution lamellae Fs15.8-22.3Wo44.7-42.0 (Fe/Mn=24-29), host orthopyroxene Fs24.4-40.8Wo2.1-2.6 (Fe/Mn=30-35).
