Writeup from MB 105:
Northwest Africa 10670 (NWA 10670) Mauritania Find: 2014 Classification: Carbonaceous chondrite (CV3) History: The stone was discovered in Mauritania in 2014 and was purchased from a Moroccan dealer at the Munich mineral fair in the same year. Physical characteristics: One brown stone of 887 g. Surface shows cavities of eroded chondrules in various colors and of white CAIs. Petrography: (R. Bartoschewitz, Bart) Microscopic examination of a thin section shows brown fine-grained groundmass, chondrules up to 1 mm (avg. 0.6 mm), and CAIs up to 15 mm. Chondrule/matrix ratio ~0.9. Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine, Fa9.0±7.4 (n=58); pyroxene, Fs0.6±0.1Wo1.3±0.9 (n=6); Ca-pyroxene, En77±18Fs2.5±1.5Wo21±12 (n=3). Kamacite Ni=5.0-6.7, Co=0.6 wt.-% (n=10). O-isotopes (R. Greenwood and I. Franchi, OU): δ17O = -1.517, δ18O = 2.759 (permil). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 3.16. Classification: Carbonaceous chondrite (CV3). Probably paired with NWA 2086. | ||||||||||||||||||||||||||||||
