Writeup from MB 105:
Northwest Africa 10566 (NWA 10566) (Northwest Africa) Purchased: 2015 Jan Classification: Lunar meteorite (feldspathic breccia) History: Purchased by Dr. David Gregory in January 2015 from a Moroccan dealer at the Tucson Gem and Mineral Show. Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed of angular mineral clasts of anorthite, pigeonite, ferropigeonite, orthopyroxene, augite, fayalitic olivine, silica polymorph, ilmenite, Cr-Ti-Fe spinel, troilite and kamacite, plus sparse rounded to angular glass fragments, set in a finer matrix. Some pigeonite grains are exsolved. Geochemistry: Low-Ca pyroxene (Fs29.8Wo5.2, FeO/MnO = 50), pigeonite (Fs23.7Wo10.0, FeO/MnO = 44), ferropigeonite (Fs55.2Wo16.2, FeO/MnO = 66), augite (Fs44.5Wo38.9, FeO/MnO = 66), fayalite (Fa71.2; Fa96.2; FeO/MnO = 82-108; N = 2), plagioclase (An94.6-97.0Or0.2-0.0, N = 2). Bulk composition (R. Korotev, WUSL): INAA of subsamples gave (in wt.%) Na2O 0.41, FeO 13.86; (in ppm) Sc 30.2, Cr 1920, Co 42.3, Ni 190, La 6.76, Sm 3.20, Eu 0.888, Yb 2.30, Lu 0.324, Hf 2.2, Th 0.93. Classification: Lunar (feldspathic breccia). Paired with NWA 7611 and NWA 8277 based on matching bulk elemental compositions. Specimens: 20 g including one polished thin section at ROM; remainder with DGregory. | ||||||||||||||||||||||||||||||
