The Neoproterozoic Trans-Angara Dike Belt, Yenisei Range, as an Indicator of Extension and Breakup of Rodinia

摘要

The issue of estimation of the geochronological boundaries in the evolution and breakup of the super-continent Rodinia is largely far from a solution. Therefore, the problem of distinguishing and dating the Neoproterozoic complexes, which mark the continental riftogenesis related to the breakup of Rodinia in the Late Neoproterozoic, is still topical [1]. In terms of modern ideas, breakups of ancient supercontinents were caused by deep mantle processes, probably induced by mantle upwellings or plumes [2].
