The problems and ways of their solution, new ideas and tasks are discussed. Modern experimental observation methods, universal software systems for their processing, methods of constructing three-dimensional models of various geological and tectonic units of Ukraine are analyzed. The results of geological and geophysical interpretation of regional and local three-dimensional models are presented. Geoelectrical heterogeneities in the Earth's crust and upper mantle of Ukraine, characterized by abnormally low and abnormally high values of electrical resistivity, are revealed. The zones of high electrical conductivity that extend to the surface are determined by subvertical heterogeneity and form a galvanically connected system. It spatially correlates with deep faults of various ranks identified by geological data. The nature of the electrical conductivity anomalies at a depth of up to 2.5 km is due to the presence of an association of conductive minerals (sulfides, graphite) in the zones of metasomatic rock processing leading to the formation of ore mineralization (uranium, gold, rare metals). In the Earth's crust at depths of 5-30 km and in the upper mantle at depths of 50-120 km, they most likely reflect traces of the influence of modern mantle fluids. According to the latest data, the nature of the anomalies is considered to be the result of the joint activity of electronic and ionic types of electrical conductivity. Anomalies in the electrical conductivity of the Earth's crust and upper mantle indicate possible zones of geodynamic activation, and deep faults are determined by zones of increased permeability through which mantle fluids are unloaded through the lithosphere. The article also highlights the connection between electrical conductivity anomalies in Ukraine and the processes of formation of oil and gas and ore deposits.
