Kolodeznikov Regularities and evolution stages, geological nature of premezosoic magmatic complex of the indigiro-kolyma region The article presents peculiarities of evolution and geological structure of the researched territory. Five stages of magmatic evolution are distinguished: earlyproterozoic, lateproterozoic, earlypaleozoic, middlepaleozoic and latepaleozoic. The premezosoic magmatic systems are brought. The Indigiro-Kolyma region magmatic evolution had three stages: nuclear, kratonic and continental-oceanic. U 17
