Writeup from MB 102:

Northwest Africa 7714 (NWA 7714)

(Northwest Africa)

Purchased: 2012

Classification: HED achondrite (Howardite)

Petrography: The fresh greyish breccia is composed of diogenetic clasts dominating over basaltic eucrite clasts set in a fine-grained clastic matrix. Diogenitic fragments are composed of large blocky orthopyroxene and Ca-rich plagioclase crystals, eucrite clasts dominated by exsolved Ca-pyroxenes and often lath-shaped calcic plagioclase. Accessories in both lithologies include silica, chromite, and troilite.

Geochemistry: Diogenitic orthopyroxene Fs25.8-30.5Wo2.1-3.6, FeO/MnO=26-38; low-Ca pyroxene Fs32.2-49.1Wo2.1-6, FeO/MnO=23-36; high-Ca pyroxene Fs60.5-63.9Wo24.8-34.5, FeO/MnO=38-56; calcic plagioclase An91.2, range An84.1-93.9.
