Applying primary data from permanent stations for geodynamic zoning
Introduction. The article focuses on present-day geodynamic motion in order to carry out geodynamic zoning of territories. Geodynamic monitoring may be both regional, for instance, of the Russian Federation, Ural region, geological rock mass, and it may also be local, i.e. covering a deposit and enclosing rock mass. Permanent stations of Global Navigation Satellite System (GNSS) have been used as a source of data for deformation monitoring.Methodology included the method of visualizing geodynamic motions according to the results of cyclic geodetic measurements which makes it possible to single out active geological structures, blocks, and tectonic faults on reasonable grounds.Results. It has been shown that it is advisable to use not modules of observation station displacement vector values but their velocities reduced to an annual cycle as a key source of information on geodynamic motion at large spatial-temporal bases. It has been indicated that an important characteristic of geodynamic motion vector field is divergence which characterizes the degree of convergence or divergence of a vector flux. Basic theses have been identified of the method of present-day geodynamic motions monitoring and visualization in the form of a vector field according to the results of cyclic geodetic measurements. Based on experimental data, it has been determined that the present-day geodynamic motion is vortical being the indicator of active tectonic faulting.
