Geochronological and isotope geochemical characteristics of mafic intrusions of the Norilsk region

Layered intrusions of the Norilsk group contain unique deposits of copper-nickel, cobalt and platinoid ores, and platinoids. The origin of silicate matrix was traditionally considered to be mantle. However, the first study of the isotopic composition of fluid components (He and Ar and sulfur) reveal...

Summary:Layered intrusions of the Norilsk group contain unique deposits of copper-nickel, cobalt and platinoid ores, and platinoids. The origin of silicate matrix was traditionally considered to be mantle. However, the first study of the isotopic composition of fluid components (He and Ar and sulfur) revealed large scale mantle-crust interaction. The complex isotopic investigations of rocks and ores of mafic intrusions of the Norilsk region performed at the Karpinskii Geological Research Institute in 2003-2008 demonstrated the quantitative genetic indicators allowing us to refine the models of the formation of unique Cu-Ni-PGE deposits.
