Writeup from MB 104:

Northwest Africa 10272 (NWA 10272)

(Northwest Africa)

Purchased: 2015 May

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Pierre-Marie Pelé and Fabien Kuntz in May 2015 from a dealer in Agadir, Morocco.

Physical characteristics: No fusion crust is evident. The interior consists of white to light-gray clasts set in a dark-gray matrix.

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed of angular mineral clasts of calcic plagioclase, pigeonite, olivine, orthopyroxene, subcalcic augite, augite, fayalite, silica polymorph, Ti-Cr-rich spinel, Al-Ti-chromite, ilmenite, rare baddeleyite and rare troilite in a finer grained matrix.

Geochemistry: Olivine (Fa18.5-35.8, FeO/MnO = 90-109, N = 3), orthopyroxene (Fs44.9Wo1.8, FeO/MnO = 70), pigeonite (Fs30.3Wo5.7; Fs25.8Wo12.1; FeO/MnO = 55-54), subcalcic augite (Fs56.5Wo25.1, FeO/MnO = 65), augite (Fs18.0Wo37.1, FeO/MnO = 56), fayalite (Fa95.6, FeO/MnO = 96), plagioclase (An88.0-96.9Or0.5-0.2, N = 3).

Classification: Lunar (feldspathic breccia).

Specimens: 15.15 g including one polished endcut at PSF; main mass is held jointly by Mr. P. Pelé and Kuntz.
