geodynamics

Purpose. Statistical information for the period from 2016 to 2021 was used to analyze seismic activity. Objective. The aim of the study is to identify the relationship between changes in water level and local seismic activity in the region. Using HPP and Psing filtering, the hypocenters of earthquakes within a radius of 30 km from the seismic station with the NDNU index were selected, and using geographic information technology tools, the hypocenters of earthquakes were compared with the geological structure of the region. Methodology.

The purpose of the work is to study the features of seismotectonics of the junction zone of the Oash and Transcarpathian faults in the Ukrainian Transcarpathians. The research methodology combines a complex analysis of geological-tectonic, seismological, geomorphological and geodetic data on the studied area. For the clarification of coordinates and depths of local earthquake foci we applied methods of their hypocenters specification, using a calculated seismological hodograph and kinematic corrections.

Objective. The protolith and tectonic settings of the Middle Eocene oil shale sampled from the outcrops and ejected products of mud volcanoes in the Greater Caucasus southeastern plunge were determined using bulk rock geochemistry data. The obtained results were adapted to the palaeogeodynamic conditions of the study areas. Method. The concentrations of element content in the samples were measured by “S8 TIGER Series 2 WDXRF” and “Agilent 7700 Series ICP-MS” mass spectrometers.

In this paper are considered the basic features of tectonic-magmatic activation’s granitoids of the Ukrainian Shield and its connection with geodynamical situations

Velocities of displacements of permanent GPS stations, located in Carpathian and Balkans region are computed. As a result directions and velocities of regional and local geodynamic movements are obtained. The estimation of the influence tereynov and suture to the modern tectonic activitythe earth's crust in the region.

The constructed model for a deep structure of the lithospere under the Neftegorsk earthquake region shows that North Sakhalin consists of the North Sakhalin sedimentary basin, the Deryugin basin and the ophiolite complex located between them. The ophiolite complex composed of the the ultrabasic rocks, fixes the position of the ancient subduction zone which was active about 100-60 million years ago. On a surface the subduction zone manifests itself as deep faults running along Sakhalin.

The thesis applies for the original geodynamical investigations of the Transcarpathians territory. New laser-digital techniques of tension and weather-temperature observations on the base of author’s implementations were used. Such techniques  allow to observe and study sub-low geological processes and movements before, during and after earthquakes, create a of tension and weather-temperature data base, make complex analyses and processing of geophysical information.

Based on the studies performed earlier [2, 3, 5], and also the problems solved by regional geodynamics [4], we propose a combined method of studying the latter - the method of processing the accumulated information about the physical fields of specific regions, adequate to the nature of the processes being studied.

Aim. Geodynamic interpretation of previously obtained 3D density and magnetic modeling results, and data on consolidated crust fault tectonics of the Dnieper part of Dnieper-Donets basin (DDB) in the light of its formation mechanism.
