To study and assess the possibility of effective application of electrical prospecting by magnetotelluric sounding (MTsounding) and to determine the range of geological problems to be solved in the geoelectric conditions of the ShuSarysu geotraverse. Methodology. The issues of methodology of modern technologies of field observations, peculiarities of processing and interpretation of MTsounding data are considered, which showed that modern instrumental and methodical electrical survey technologies of MTsounding allow obtaining results of field measurements of increased reliability, due to their accuracy, productivity, mobility, noise immunity, level of automation. To identify the main features of the geoelectric structure of the Earth’s crust and the upper mantle, the modern technique of interpreting MT data allows for 1, 2D inversion of the effective curves of apparent resistivity and impedance phase. Findings. Based on MTsounding data, a geoelectric section of the ShuSarysu geotraverse was constructed, characterizing the position and morphology of five geoelectric boundaries in the crustal section in the 0–40 km depth interval. The identified five geoelectric horizons show good coincidence with the conventional seismic horizons and confidently correlate with the geological references established by GIS data. Originality. On the basis of MTsounding studies, the geological interpretation of the structure of suprasalt and subsalt structuralformation complexes is presented; the geological efficiency of MTsounding electrical prospecting in revealing the complex structures in the conditions of the ShuSarysu geotraverse is shown. On the basis of model constructions of the geoelectric section, new data on the deep geological structure of the ShuSarysu geotraverse were obtained: new data on the structure of Mesozoic terrigenoussedimentary rock complexes and the Paleozoic part of the section with the allocation of the supposed faults; on the basis of MTsounding results, recommendations for further detailed geological exploration work were given. Practical value. A comprehensive interpretation is recommended of the obtained MTsounding data together with the results of geological and geophysical research on the regional profile in order to establish search criteria for the discovery of mineral deposits and the prospects of gas content in the areaDOI

Практическое значение
The results of magnetotelluric investigations made it possible to refine the deep geoelectrical structure of the Earth's crust along the Shu-Sarysu geotraverse, identify major geoelectrical horizons and inferred fault zones. The obtained data can be used for planning regional and detailed geological exploration programs, assessing the mineral and hydrocarbon potential of the area, and selecting promising targets for further geophysical surveys and exploration activities.Квартиль
