The petrological–geochemical and isotopic–geochronological studies of contrasting rocks of the Yenisei Regional Tectonic Zone of the Yenisei Ridge allowed identification of the period of formation of riftogenic structures accompanied by intraplate magmatism. The extension processes are reflected in dike swarms of bimodal associations of anorogenic granites and intraplate mafic rocks with an intrusion age of 797–792 Ma. The formation of this belt is related to the Neoproterozoic extension along the western margin of the Siberian Craton, which occurred during breakup of the Rodinia Supercontinent and origination of the Paleoasian Ocean.
