Abstract:

According to the results of fi eld research on Spitsbergen and Franz Josef Land and analysis of marine geological and geophysical data and published materials, the spatial and temporal characteristics of the Jurassic-Cretaceous plume magmatism in connection with geodynamics of destructive transformation of the lithosphere of the Arctic in the context of the formation of the Amerasian basin and Canadian Trench are presented. Staging and polycyclic multiphase of plume magmatism is substantiated, and refl ected in geochronology of formation of its provinces in the Arctic region.
