FORECAST-EXPLORATION MODEL OF GOLD DEPOSITS ASSOCIATED WITH GRANITOID INTRUSIONS OF THE RUSSIAN ARCTIC ZONE

The article presents a exploration model that summarizes the most important characteristics of intrusions related gold deposits (IRGS) in relation to the Arctic zone of Russia. In the North-East of Russia, such deposits are called gold-rare-metal deposits (GRMD), due to the noticeable admixture in ores Bi, Te, W, Co and Sn. The presented model is based mainly on the results of studies of the North-East of Russia GRDM, as well as on the data of foreign researchers who studied IRGS deposits of Tintin metallogenic belt, located in Northern Canada (Yukon) and Alaska. In the geological part of the model, classification features of GRDM are emphasized in relation to other types of hydrothermal magmatic systems. The most important, in our opinion, indicator factors in the formation of GRDM are put forward to the fore. The article shows that in economically undeveloped regions of the Arctic zone of Russia the most interesting the rich vein of Pogo type deposit (Alaska, USA), Shkolnoe (Magadan area) and Kekurnoe (Chukotka). On the territory of the European part of the Arctic zone, in the more developed old industrial regions of the Kola Peninsula, Karelia, Arkhangelsk region and the Polar Urals are also industrially important stockwork large GRMD (such as Fort Knox, Alaska, USA).
