Northwest Africa 8482 (NWA 8482)

(Northwest Africa)

Purchased: 2013 June 7

Classification: HED achondrite (Eucrite, polymict)

History: Purchased in Erfoud, June 2013

Physical characteristics: A single crusted full stone. Cut surface reveals light gray interior with lighter mm-sized clasts.

Petrography: (C. Cournède and J. Gattacceca, CEREGE) Basalt with sub-ophitic texture. Mm-sized clasts with cumulate texture. Main minerals are plagioclase (~250 μm) and clinopyroxenes (~400 μm). Accessory silica (~90 μm), chromite (~100 μm). Rare metal.

Geochemistry: Basaltic host orthopyroxene Fs61.3±1.1Wo1.9±0.2 (n=10). Cumulate clasts Fs42.3±5.5Wo2.4±0.7 (n=5). Augite exsolutions Fs25.3±4.4Wo42.7±1.5 (n=4). Plagioclase An88.3Ab11.2 Or0.5 (n=2). Magnetic susceptibility log χ = 3.32 (χ in 10-9 m3/kg).

Classification: Eucrite polymict. Minimal weathering

Specimens: 5.2 g and a polished section in CEREGE. Main mass with P. Thomas
