Numerical simulations of the current channeling effect on MT responses due to shallow conductive structures

MT data obtained at an alluvial valley in Argentina showed a strong telluric current channeling along its axis. This effect was reflected in the MT curves as a very low response for the TM apparent resistivity for periods longer than 1 s. The cause of this channeling remained unsolved although the e...
