The main objective of our research is to: 1) conduct a correlation analysis of the relationship between geoid heights and topographic heights in the modern era using calculated moving correlation coefficients (MCC); 2) extrapolate the obtained correlation model to past geological epochs and determine the paleogeoid using known surface heights derived from paleoDEM continental reconstruction models (Scotese and Wright, 2018); 3) perform calculations of changes in "True Polar Wander" (TPW) based on the obtained paleogeoid height data sets resulting from the movement of lithospheric plates.

The purpose of the work is to present widely to the scientific community and analyze in detail the structure and oil and gas bearing of the Bukovyna lithosphere (the eastern part of the Carpathian region of Ukraine) based on the unique data on the regional RWМ-CDP profile RP-5 and on the neighboring regional profiles with the involvement of other geological and geophysical data.

The purpose of research is to identify horizontal deformation of the Ukraine territory, using only proven and suitable for geodynamic interpretation GNSS stations. The initial data are observations from 30 GNSS stations for 2017 to 2020. Methodology. The methodology includes the analysis of modern Earth's crust deformations of Ukraine. As a result, for the first time the impact of the coordinates time series created by two different methods: Precise Point Positioning (PPP) and the classical differential method, on determining deformation processes was analysed.

The study aims to determine and interpret the distribution of the global tangential mass force (TMF) vector field by azimuthal orientation and intensity. Using cluster and correlation analysis, we compared the direction of the TMF vector field with the direction of movement of permanent GNSS stations and the direction of movement of the GSRM model continental velocities from the Global Strain Rate Map Project. Methodology. The author continues their study of additional planetary stresses in the lithosphere caused by distributed mass forces.

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.
