Post-Tectogenic Events and Exhumation Processes in Svekokarelides of the Ladoga Region

Abstract

Elements of the structure of the Svecokarelian pericratonic zone of the Karelian Massif (SE Fennoscandia), formed after the main events of the Svekofennian tectogenesis, have been identified and characterized. Dated age intervals of the orogenic stage and post-orogenic extensional collapse manifestation, determined the depth levels of the corresponding structures and visualized the scheme of differentiated exhumation of the deep complexes of the post-Proterozoic Savo-Ladoga movable zone. Approximate estimations of exhumation rates of deep material at certain stages of the Precambrian evolution of this zone are given.
