Abbreviation: NWA 10644 Observed fall: No Year found: 2016 Country: (Northwest Africa) Mass 166 grams Classification history:Meteoritical Bulletin: (2016) Lunar (feldsp. breccia)Recommended: Lunar (feldsp. breccia) This is 1 of 236 approved meteorites classified as Lunar (feldsp. breccia). Comments:Approved 15 May 2016 Northwest Africa 10644 (NWA 10644)(Northwest Africa)Purchased: 2016Classification: Lunar meteorite (feldspathic breccia)History: Purchased by Dustin Dickens, February 2016, from a Moroccan dealer and sold to Mendy Ouzillou.Physical characteristics: Single stone, irregular exterior, no fusion crust. A saw cut reveals light-gray feldspathic clasts (up to 1 cm) and some smaller, fragmental, white plagioclase grains set in a dark-gray groundmass.Petrography: (C. Agee, UNM) This is a feldspathic breccia showing several different textural domains: 1) poikilitic plagioclase with olivine and pyroxene inclusions, 2) zones of fragmental plagioclase, olivine, and pyroxene, 3) cataclastic zones of fine-grained (~20 μm) silicates, 4) vesicular shock melt veins and pockets. Pigeonite and augite show significant igneous, iron-enrichment trends.Geochemistry: (C. Agee and M. Spilde, UNM) Olivine Fa37.9±1.6, Fe/Mn=98±6, n=13; pigeonite Fs39.3±13.9Wo17.0±4.1, Fe/Mn=66±9, n=11; augite Fs32.0±22.7Wo37.4±1.1, Fe/Mn=60±20, n=2; plagioclase An97.6±0.5, n=5; Shock melt (20 μm defocused electron beam, proxy for bulk meteorite composition): SiO2=44.7±0.1, TiO2=0.5±0.1, Al2O3=29.2±2.5, Cr2O3=0.09±0.05, MgO=4.0±1.4, FeO=5.3±1.7, MnO=0.06±0.02, CaO=16.4±1.0, NiO=0.03±0.02, Na2O=0.48±0.01, K2O=0.10±0.01 (all wt%), n=5.Classification: Lunar (feldspathic breccia)Specimens: 20.73 g including a probe mount on deposit at UNM; Mendy Ouzillou holds the main mass.
