Siberian traps and Pt-Cu-Ni deposits in the Noril’sk area / Сибирские траппы и платино-медно-никелевые месторождения норильского региона

In previous years, the genesis of uniquely large mineral deposits became one of the most urgent geological problems because of the key role played by giant deposits: accounting for <5 % of the currently developed mineral deposits, these deposits satisfy 85 % the world’s consumption of mineral resources. The development of these deposits should provide a basis for the stable progression of our civilization (Rundkvist and Kravchenko 1996 ). Another important aspect in the analysis of super-large mineral deposits is their genesis because these deposits are, in fact, giant geochemical anomalies in the Earth’s crust (e.g., the PGE concentrations in the Noril’sk ores are six to seven orders of magnitude higher than those in the clarkes) <...>
