Main stages of tectonic transformation of large landforms of the Kola Peninsula during the Phanerozoic

Abstract

Three most important fundamentally different stages are identified in the Pre-Cambrian and Phanerozoic history of the Kola Peninsula topography. During Pre-Cambrian the landforms were pre-conditioned by tectonics and evolved under condition of the geosynclinals processes action. Most important regional transformation of topography took place during Middle Paleozoic induced by tectonic activity within the Middle Paleozoic rift zone. Neotectonic (Post-Paleogene) stage is mostly marked by block morphostructures formation controlled by active faults of the earthcrust. The mentioned processes are imprinted in various relict landforms and correlative sediments, thus the importance of paleogeomorphological studies being proved for analysis of tectonic evolution of a region and metallogenic zones characteristics.
