Аннотация: Potential ore content of basic intrusions intersected by oil and gas prospect and exploratory wells in the Yenisei range in the west of the Siberian platform is proved based on the petrological and petrochemical analysis data. The characteristic is given to the Oneka stratified, potentially metalliferous intrusive complex, prospectПоказать полностьюs are outlined for finding Norilsk-type copper-nickel ore in geoblocks of basic intrusive rock mass, and information on high-rate gas flow in appraisal wells drilled in the Moktakon area and other sites where stratified magnesium-bearing basic intrusions have been revealed is reported in the article. The Oneka intrusive complex is characterized by the data of hundreds of chemical analyses of rocks sampled in horizontal and vertical drill holes. Basic rock-forming minerals are found to be olivine, pyroxenes, plagioclases, ferrous and titanium oxides; distribution of iron group elements (V, Cr, Ni, Co) and rare earth elements is examined. Based on the petrological characteristics, congruence with ore-bearing intrusions of the Norilsk region is revealed. The research has confirmed the earlier data on paragenesis of gas-and-oil fields and ore deposits and enabled assigning a new research objective. It is suggested to continue the geological investigation of the region based on a synergetic approach, with accounting for occurrence of the Norilsk-type sulfide ore-bearing intrusions in geoblocks. The research was supported by the RF Ministry of Education and Science.
