Co-Ni arsenide ores in carbonate veins.
This deposit (Smirnov, 1978; Borisenko and others, 1984; Lebedev, Cherezov, 1989; Lebedev, 1998) consists of carbonate veins with arsenide Ni-cobalt minerals. The host rocks are metasomatically altered and consist of Silurian limestone, Carbonaceous sandstone and siltstone, and Early Devonian porphyry and tuffaceous conglomerate that are intruded by Late Devonian to Early Carboniferous gabbro and syenite plutons.
