Summary:

The relevance of the work lies in the use of remote geophysical methods for geological mapping of the tectonic features of the crystalline basement of the earth’s crust, overlain by rocks of the sedimentary cover of the earth’s crust. This significantly increases the informativeness and efficiency of predictive prospecting for deposits of various minerals (oil, natural gas, coal, ores). At the same time, some Russian researchers have hypothesized the relationship between the spatial location of deposits of gaseous and liquid hydrocarbons and concentric morphological structures of the central type — the outcrops of mantle plumes to the surface of the crystalline basement of the Earth’s crust. The purpose of this article is to show experimentally, using magnetic and gravitational data, the possibilities of regional geological and geophysical research methods for searching and studying the structure of concentric morphological structures of the central type. In addition, it is proposed to confirm the hypothesis of a correlation between the predominant spatial location of deposits of various types of minerals in zones of concentric morphological structures of the central type formed by mantle plumes on the surface of the crystalline basement of the Earth’s crust, on the territory of the central regions of the East European Platform. Various geological and geophysical methods (magnetic, gravitational, deep geological and geophysical sections of the lithosphere) were used as research methods for searching and in-depth study of the structure of “root” inhomogeneities of concentric morphological structures of the central type, including methods of decoding satellite images. As the results of the study, the results of the forecast assessment in the central regions of the East European Platform (Ryazan-Saratov trough, Moscow syneclise, Kursk magnetic anomaly zone) are presented in order to identify areas promising for the search for mineral deposits.
