Distinguishing of faults and determination their tracing depth by electromagnetic sounding

As is known, deep faults exert considerable influence on formation of the regional block structure of individual areas. They are one of important factors for formation and accumulation of useful minerals including oil and gas. Besides this accurate distinguishing of faults, determination of their orientation and tracing through the depth are very important to study and prognosticate earthquakes because of that site zones of earthquakes are mainly associated with the areas of intersection of faults. Definite criteria to single out deep faults both the ones traced at the surface and buried by young deposits are characteristic to geophysical methods and particularly to seismic and gravity prospecting.
