Abstract
The Pt–Cu–Ni Noril’sk deposits were discovered in the nineteenth century on the SW Siberian Platform. They are located in a paleorift zone and display a structure that differs from that of the Siberian craton basement. Terrigenous and carbonate rocks with anhydrite and coal are exposed on the surface of the Noril’sk area. They are overlapped by volcanic rocks of the trap formation. The stratigraphy of the sediments and tuff–lava deposits is given. The intrusive rocks consist of 10 % plutonic rocks and are represented by ultrabasic to basic intrusions (sills, dykes) of mostly normal alkalinity and rarely of elevated alkalinity. There are two types of sulfide ores: disseminated and massive. These are located near the contacts with the intrusive bodies. There are three main deposits in the Noril’sk area: the Talnakh, Oktyabr’skoe, and Noril’sk deposits. Many other intrusions contain mineralizations in economic quantities.
