Writeup from MB 106:

Northwest Africa 11167 (NWA 11167)

(Northwest Africa)

Purchased: 2014

Classification: HED achondrite (Howardite)

History: The meteorite was bought in 2016 from a meteorite dealer in Erfoud, Morocco.

Physical characteristics: Fourteen grayish fragments with some fusion crust.

Petrography: The meteorite is a breccia composed of abundant mineral and subordinate lithic clasts (basaltic and impact melt clasts) set into a finer grained matrix. Main minerals are exsolved pyroxene, diogenetic orthopyroxene (10-15%) and calcic plagioclase. Accessory phases include silica, chromite, FeS, FeNi-sulfides, and metallic Fe.

Geochemistry: pyroxene host to augite lamellae: Fs59.5±2.4Wo3.6±1.6 (Fs55.7-62.2Wo2.0-6.0, n=11, FeO/MnO=29-34); Ca-pyroxene: Fs25.9±2.4Wo41.8±2.4 (Fs24.1-33.9Wo33.6-43.0, n=13, FeO/MnO=29-36); diogenitic pyroxene: Fs24.1±0.4Wo2.2±0.2 (Fs23.5-24.7Wo1.9-2.4, n=11, FeO/MnO=26-30); calcic plagioclase: An88.6±3.5 (An83.5-94.8, n=18)
