Abstract
The results of combining remote methods (satellite imagery and geoelectric measurements) to research the territory near Lebyazhij pond in Southern Kryvbas (Ukraine) are shown. The aim of research was to localize sources of highly saline water. Satellite data (integration of digital maps of multispectral images, interpretation and construction of lineament maps of tectonic structures and geodynamic zones with their analysis and tectonophysical interpretation) were used at stage of preparation, field work and interpretation of the results of geophysical measurements. To research the characteristics of the geoelectric parameters of the geological section, vertical electric sounding (VES) was carried out. The areas of local flooding with mineralized waters and waterlogging were identified. They are associated with complicated structure of intersection of differently oriented tectonic faults with submeridional Tarapakov thrust zone in Precambrian basement. Interferometric image processing (2015–2018) shows modern subsidence of Earth’s surface here. Using geoelectric data, a map of depths of Precambrian rocks with local depression under Lebyazhij pond was constructed. It is due to specific articulation of misaligned discontinuous faults. Here the lenses of highly mineralized waters are preserved in the Kryvyi Rih fault system. The constructed horizontal sections according to VES data show migration of mineralized waters at different stratigraphic levels, which can lead to the development of landslide processes along the left bank of the Ingulets river.
