Northwest Africa 14041 (NWA 14041)
Classification: Lunar meteorite (feldspathic breccia)
History: Found in Mali by camel shepherds in January 2021 and subsequently purchased in Algeria by Ahmed Salek.
Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Breccia composed of mineral clasts of anorthite, olivine, low-Ca pyroxene, pigeonite, exsolved pigeonite and minor Ti-chromite set in a fine grained matrix containing minor secondary calcite and a K-Ca-bearing zeolite phase.
Geochemistry: Olivine (Fa29.0-51.5, FeO/MnO = 99-102, N = 4), low-Ca pyroxene (Fs23.3Wo3.7, FeO/MnO = 60), pigeonite (Fs32.6-68.1Wo8.7-19.5, FeO/MnO = 52-75, N = 4), pigeonite host (Fs42.0Wo10.4, FeO/MnO = 66), augite exsolution lamella (Fs22.1Wo40.6, FeO/MnO = 71), anorthite (An90.8-96.0Or0.1, N = 3).
Classification: Lunar (feldspathic breccia).
