Writeup from MB 105:

Northwest Africa 10479 (NWA 10479)

(Northwest Africa)

Purchased: 2015

Classification: HED achondrite (Eucrite, brecciated)

History: The meteorite was purchased from the Moroccan meteorite dealer Smara Addi.

Physical characteristics: One small individual partly covered with fusion crust was recovered from the north-African Sahara.

Petrography: The meteorite is a breccia composed of lithic clasts set into a fine-grained matrix. Lithic lasts are dominantly coarse-grained basaltic. Most abundant minerals are exsolved pyroxenes and plagioclase, less abundant are chromite, pyrrhotite and SiO2 polymorphs. Some shock melt veins are present.

Geochemistry: low-Ca pyroxene: Fs31.8±3.3Wo6.9±1.6 (Fs28.4-40.2Wo5.2-10.2, n=27, FeO/MnO=26-31); Ca-pyroxene: Fs53.6±9.6Wo22.5±2.7 (Fs39.5-74.1Wo18.2-27.9, n=34, FeO/MnO=27-38); calcic plagioclase: An85.2±2.9 (An79.5-92.3, n=25)
