Geodynamically active zones include zones of tectonic stress concentration and crustal deformations. They are characterized by increased values of stress state of fracturing, permeability, engineering-geological properties of geological environment, as well as geophysical anomalies, specific development of related exogenous processes. As an example, the Seversk-Donets neotectonic zone of structural unconformities and increased geodynamic activity in the area of junction of the southern wing of the Voronezh arch with the Donetsk ridge and the Karpinsky rampart are considered. New data on the right thrust stresses in this zone, as well as mining-geological and geo-environmental aspects of its manifestation are discussed.
Geodynamically active zones are neotectonic linear structures separating crustal blocks of different ranks, in which these blocks interact with each other. For this reason, such zones are in a relatively high stress state. The degree of activity of such zones depends on the amplitudes of tectonic movements, the types of these movements and the style of interaction between the blocks. Their activity is well reflected in the relief. The ecological significance of such zones has been assessed. The tectonic structure and geomorphologic appearance, conditions and history of formation of some geodynamically active zones have been studied. They have different ranks and scales, depth of occurrence, size and age. These are the Ox-Don trough with internal zones of the second order in the center of the Russian plate, the Urzhumo-Orenburg zone of structural discordance in the east of the same plate, the Kuloi-Lou Pinega zone in the northernmost part of the Russian plate and some others.
