gravitational anomalies

On the question of the geological nature of the crystalline basement inhomogeneities of the East European Platform

Based on the analysis of gravitational and magnetic anomalies of the eastern part of the East European Platform, it is concluded that inhomogeneities caused by serpentinization processes are present in the Earth’s crust. This conclusion is confirmed by conducting geological and geophysical studies on reference objects with serpentinite outcrops.

Some regularities of change in density in the lithosphere of Northern Eurasia

A method is proposed for calculating the normal compaction curve of rocks for the deep parts of the lithosphere. It is based on the analysis of petrophysical characteristics and interpretation of gravitational anomalies. The main regularities of density changes in the lithosphere of Northern Eurasia are investigated.

Results of Application of the Oil and Gas Potential Preliminary Assessment Exploration Technology over the Potential Area of Saratov Region

To improve the efficiency of geophysical prospecting, the Department of Geophysics of the Faculty of Geology of Saratov State University develops original complexation technology allowing to evaluate the possibilities of identifying promising oil and gas areas by circular thermal-magnetic anomalies, limited to the gradient zones of areas of gravimagnetic complex parameter or geopotential fields anomalies itself. The article presents the experience of applying non-seismic elements of the complex of this technology.
