Abstract

The profile line of geophysical exploration lies along the fairway of the Lena River. A complex of transient electromagnetic soundings (TES) and a common deep point (CDP) method has been used for the exploration. A complete geoelectrical section of sedimentary deposits and the properties of the basic geoelectrical layer have been estimated using TES. In the sedimentary deposits productive layer zones with increased and decreased electrical resistance have been studied. The results of both geoelectrical and seismic analyses prove that the use of both of these methods is very promising.
