Complex geophysical research of the Vychegda depression fault zones

The article presents the results of complex geophysical studies of the fault zones of the Vychegda depression. At the first stage of the investigation, fault tracing was performed based on seismic data and potential fields, followed by radon monitoring. The results showed that the faults of the Vychegda depression were reliably identified in seismic time sections. According to the data of potential fields, faults were most distinctly expressed in a magnetic field. In the radon field, the dislocations corresponded to the areas of increased the volume radon activity. Using the methods listed above, the Vychegodsko-Lokchimskiy, Keltminskiy, and Visherskiy faults were identified and the location of the Predtimanskiy fault was corrected. Thus, the presented complex of methods allows mapping the faults covered by the sedimentary cover within the platforms.
