Northwest Africa 10609 (NWA 10609)

(Northwest Africa)

Purchased: 2016

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Gary Fujihara from Morocco, 2016.

Physical characteristics: Single stone, weathered exterior without fusion crust. Cut and polished surface reveals numerous white feldspathic clasts set in a dark-gray groundmass. Some of the feldspathic clasts have a reddish tint.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows a fragmental breccia with numerous olivine, pigeonite, and augite grains set in a dominant feldspathic matrix. Lithic and melt clasts with vesicles were also observed.

Geochemistry: (C. Agee and M. Spilde, UNM) Olivine Fa38.9±14.5, Fe/Mn=94±8, n=11; pigeonite Fs39.4±7.5Wo9.2±6.1, Fe/Mn=61±4, n=8; augite Fs21.1±4.7Wo38.3±3.4, Fe/Mn=50±4, n=3; plagioclase An95.7±0.7, n=6.

Classification: Lunar feldspathic breccia
