Writeup from MB 109:
Northwest Africa 13119 (NWA 13119) Mauritania Purchased: 2019 Classification: Lunar meteorite (feldspathic breccia) History: Purchased from a Mauritanian meteorite dealer by Edwin Thompson and Phillip Todd in August of 2019. Physical characteristics: Three pieces that fit together. No fusion crust. Saw cuts reveal a fragmental breccia with numerous angular shaped, cm-sized, white feldspathic clasts set in a predominantly light gray groundmass. There are also a few scattered brown-green lithic clasts present. Petrography: (C. Agee, UNM) SEM images show fragmental breccia of differing grain-size scales. The groundmass is extremely fine-grained with cataclastic domains, and a variety of micro-basaltic lithologies and single-phase fragments of olivine, pyroxene, and plagioclase. Ubiquitous shock melt veins and vesicles are present throughout. Geochemistry: (C. Agee, UNM) Olivine Fa25.6±10.7, range Fa8.1-41.2, Fe/Mn=114±26, n=7; pigeonite Fs24.4±8.9Wo10.1±2.0, Fe/Mn=48±2, n=2; augite Fs16.8±1.0Wo31.7±10.1, Fe/Mn=58±8, n=3; plagioclase An95.4±0.8, n=4; shock melt (proxy for bulk composition) SiO2=45.0, TiO2=0.37, Al2O3=29.7, MgO=6.2, FeO=2.3, MnO=0.07, CaO=15.7, Na2O=0.45 (wt%). Classification: Lunar, feldspathic breccia Specimens: 28.7 g on deposit at UNM, Phillip Todd holds the main mass. | ||||||||||||||||||||||||||||||
