Northwest Africa 10895 (NWA 10895) Mauritania Purchased: April 2016 Classification: Primitive achondrite (Acapulcoite) History: Found by meteorite hunters during an expedition near the Western Saharan, Algerian and Mauritanian border region. Purchased in Mauritania. Physical characteristics: Single stone. A saw cut shows a mosaic of dark gray grains, most of which appear to be less than 1 mm in diameter. Petrography: (C. Agee, UNM) This meteorite consists primarily of high-Ca pyroxene and olivine with most grain sizes in the probe section in the range 200-500 μm, there were also a few percent low-Ca pyroxene and plagioclase detected. Fe-Ni metal and oxidized metal is abundant, particularly as veins and along grain boundaries. Geochemistry: : (C. Agee and M. Spilde, UNM) High-Ca pyroxene Fs6.1±0.4Wo42.0±1.8, Fe/Mn=11±1, Cr2O3=1.4±0.2 (wt%), n=5; olivine Fa13.8±0.3, Fe/Mn=25±1, n=6; plagioclase Ab76.7±2.7An20.5±3.2Or2.8±0.5, n=3. Classification: Acapulcoite, not a lodranite, based on grain size of pyroxene and olivine, and the presence of plagioclase. Specimens: 22 g including a probe mount on deposit at UNM, DPitt holds the main mass. | ||||||||||||||||||||||||||||||
