EFFICIENCY OF A COMPLEX OF GEOPHYSICAL METHODS IN THE ALLOCATION OF VOLCANO-TECTONIC STRUCTURE IN THE ZEYA-BUREYA BASIN

The research is aimed at the identification of the structural and tectonic features of the Zeya-Bureya depression by a set of geophysical methods of electrical prospecting and seismic measurements under mineral deposit exploration. The differential sections of resistance were built at the stage of quality analysis of the electroprospecting data using the method of "conducting plane". The data of electrical prospecting and seismic measurements were integrated. The results of integrated interpretation of seismic measurements and electrical prospecting data under the search for hydrocarbons on the territory of the Amur region (Zeya-Bureya basin) allowed to discover volcanic edifices, which could have a significant effect both on the catagenesis of organic matter of sedimentary rocks and the preservation of hydrocarbon traps. Therefore, the integration of geophysical methods at the stage of qualitative analysis allows reliable mapping of the tectonic structures of different order.
