Northwest Africa 1694


Found 2002

Carbonaceous chondrite (CK3)

A 47.1 g stone was purchased in Safsaf, October, 2002. Mineralogy and classification (T. Bunch and J. Wittke, NAU): fresh stone (shiny fusion crust with slight interior staining near the surface) with 80 % fusion crust. Modes ( in vol%): matrix, 47; chondrules, 44; sulfides, 6; Cr-magnetite, 2; refractory inclusions, 1. Chondrules range in size from 0.08 to 1.2 mm. Matrix mostly unrecrystallized, fine-grained (<5 µm) olivine, Fa37; augite, Fs15Wo47; Ca-poor pyroxene, Fs29; Ni-rich sulfides (Co up to 0.84 wt %) and Cr-rich magnetite (Cr2O3 up to 15.1 wt %). Sulfides contain many small (<20 µm), rounded inclusions of Cl-apatite and SiO2 glass. Similar to, but not paired with NWA 772. Contains Ca,Al-rich inclusions. Shock level, S1; weathering grade, W0/1. Specimens: type specimen, 9.42 g and one thin section, NAU; main mass, xHupé.
