Abstract
To determine the nature of the contribution of current tectonic processes to the formation of morphostructural ensembles is an important task. This can be done by comparing the morphostructure with the expected consequences of the impact of geodynamic systems. In the border area of the Baltic Shield and the Russian Plate, within the Circumbaltic zone of dislocations, there is a chain of recent graben depressions. The location of the depressions is determined by the tectonophysical patterns of dislocation sampling and favorable local structural conditions. Depression arose as areas of tension with the superpositional interaction of two subordinate horizontally oriented newest geodynamic systems – pressing the Baltic shield onto the Russian Plate and pushing the geological substrate at the point of their junction in the perpendicular direction. In the northern part of the White Sea Depression, the “visor” of the Karelian massif is approaching to the region of oncoming progressive stretching around the Kandalaksha graben. The superposition of these processes is clearly expressed in relief. Thus, the formation of morphostructures in the area is strongly influenced by the interaction of geodynamic systems.
