The purpose of the presented work was to model the electrical conductivity distribution in the northwestern part of the Ukrainian shield and to study the relationship of geoelectric anomalies with natural mineral deposits and with signs of possible tectonic activation of long-lived fault systems on the Shield. The methodology was based on long-period magnetotelluric and magnetovariational measurements in the period range of 3-16 to 2500-3600 s.

The aim of this research is to detect the connection between geomagnetic and radon anomalies in the area of  Kyiv Ukraine,  studying the geoecological situation of the territory, and assessing its ecological safety. Geomagnetic and radon abnormal fields are significant geophysical factors of the environment, which largely determine the ecological state.

The preliminary interpretation results of monitoring data of hydrodynamic parameters of groundwater in Dnepropetrovsk region for the purpose of neotectonic changes forecast in the massifs are given. The necessity of creation the national data base of monitoring results of groundwater hydrodynamic parameters, executed at all regions of Ukraine, is pointed out.

Some features of methodical means of petrovelocity thermobaric modeling have been considered. Аn example of the construction of a deep petrovelocity model of a crust part of the Ukrainian Shield is given and analysed.

seismogeological model of the Kirovograd ore district, it reflects its modern deep structure. The new interpretation of the seismic data has identified a correlation surface structures in the region with a relief Moho and local inhomogeneities of the crust. As a result, the connection established areas with a high concentration of ore with deep sublatitudinal deflection in the relief of the Moho. Originality For the first time MCWE seismic data processed using statistical analysis, maps of Moho, K2 and seismogeological 3D model of the Kirovograd ore district. The practical significance.

Based on the results of three-dimensional gravity modeling, listric faults have been mapped on the Ukrainian Shield for the first time. The relationship of the faults with ring structures has been established.

Purpose. To present the summary of findings of the geotectonic analysis of the basement of the Ukrainian Shield (US) and to give grounds for the specific conditions of its formation in the Early Precambrian. Methodology. Conducting analysis using the latest results of the of morphoparagenetic geological-formational studies and concepts as to the layer-block structure of the region. Results.

Purpose. Lithosphere Ukrainian shield (US) presented of the mosaic blocks that have a different configurations in a different times and belong to different continental fragment in early Archaean probably. Geodynamic models are exist in the present time of the northwestern (Volyn, Bug, Rosinsk blocks) and central (Ingul block) parts of the US that are not related. Construction of a common model geodynamic development of the entire western part of the US is not yet possible in the Proterozoic that is important to solve paleogeodynamic issues in the Precambrian.
