Writeup from MB 106:

Northwest Africa 11165 (NWA 11165)

(Northwest Africa)

Purchased: 2016

Classification: HED achondrite (Eucrite, brecciated)

History: The meteorite was bought in 2016 from a Moroccan meteorite dealer at a mineral fair in Munich, Germany.

Physical characteristics: Many dark-brownish individuals without fusion crust.

Petrography: The meteorite is a breccia composed of basaltic and impact melt fragments set into abundant clastic matrix. Basaltic clasts and matrix are dominated by exsolved pyroxene and calcic plagioclase up to 1mm in size. Minor phases are silica, chromite, FeS, FeNi metal, and ilmenite. No metallic Fe was found. The meteorite is cut by several shock melt veins.

Geochemistry: low-Ca pyroxene: Fs43.2±14.6Wo2.8±0.6 (Fs21.7-60.0Wo1.8-4.5, n=39, FeO/MnO=26-32); Ca-pyroxene: Fs28.6±0.5Wo41.3±0.5 (Fs27.9-29.7Wo40.6-42.1, n=15, FeO/MnO=28-31); calcic plagioclase: An92.0±1.1 (An90.7-93.3, n=19)
