Northwest Africa 14188 (NWA 14188)
Lunar meteorite (basaltic breccia)
History: Found in Niger and purchased by Craig Zlimen in February 2021 from an Algerian dealer.
Petrography:(A. Irving, UWS and P. Carpenter, WUSL) Breccia composed of basaltic lithic clasts and related crystalline debris (predominantly olivine, pigeonite, subcalcic augite and anorthite) in a finer grained matrix. Accessory phases are Ti-chromite, troilite, kamacite (fresh to partly altered) and minor secondary barite.
Geochemistry: Olivine (Fa37.1-39.1, FeO/MnO = 102-117, N = 4), pigeonite (Fs26.1-28.0Wo9.4-11.4; Fs24.6Wo18.8; FeO/MnO = 56-62; N = 3), subcalcic augite (Fs21.4Wo25.0, FeO/MnO = 55), anorthite (An95.4-95.6Or0.3-0.2, N = 3).
Classification: Lunar (basaltic breccia).
Specimens: 20.0 g including one polished endcut at UWB; remainder with Mr. C. Zlimen.
I have not studied Northwest Africa 14188.
