Writeup from MB 106:

Northwest Africa 11166 (NWA 11166)

(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: Small individual partly covered by fusion crust.

Petrography: The meteorite is a breccia composed of fine- and coarse-grained basaltic clasts set into a clastic matrix. Exsolved pyroxene and calcic plagioclase are the most abundant minerals in all lithologies. In the clasts their grain sizes vary between about 30-400 µm. Exsolution lamellae in pyroxene are ~1 µm wide. Minor phases include silica, chromite, FeS, FeNi metal, ilmenite, and fayalite. No metallic Fe was found.

Geochemistry: pyroxene: Fs49.8±2.6Wo15.4±3.6 (Fs44.7-53.8Wo6.9-22.9, n=26, FeO/MnO=30-34); calcic plagioclase: An86.8±2.3 (An82.2-90.2, n=12)
