Writeup from MB 109:

Northwest Africa 13160 (NWA 13160)

(Northwest Africa)

Purchased: 2019

Classification: HED achondrite (Eucrite)

History: The meteorite was purchased from a Morrocan dealer at the mineral show in Munich, Germany.

Physical characteristics: Greyish rock with some fusion crust.

Petrography: The meteorite is a fine-grained fragmental breccia composed of basaltic clasts and black melt rock clasts up to 2 mm in size set into a clastic matrix. Basaltic clasts and matrix are dominantly composed of exsolved pyroxene and plagioclase grains up to 900 µm in size. Some pyroxenes show compositional zoning indicating a low degree of thermal metamorphism. Minor phases include silica, FeS, chromite, ilmenite, and metallic iron.

Geochemistry: low-Ca pyroxene: Fs41.0±9.1Wo5.8±1.2 (Fs28.8-53.7Wo3.5-8.1, FeO/MnO=24-30, n=17); Ca-pyroxene: Fs34.4±9.4Wo36.7±6.2 (Fs24.5-48.4Wo26.4-43.5, FeO/MnO=25-29, n=22); calcic plagioclase: An91.6±0.4 (An90.7-92.0, n=12)
