- Аннотация: Numerical modeling was performed to understand main peculiarities of EM field behavior in typical marginal sea settings and to study the resolution of EM field to deep conductors. A number of idealized conductivity structure models of Japanese subduction zone of different complexity were constructed. MT-response sensitivity to conductive asthenosphere beneath marginal sea and conductive zone beneath volcanic arc was estimated. Conductive asthenosphere causes essential distinctions in resulting response (up to XXX percent of amplitude and 10° of phase), so it can be confidently resolved. Another conductor (beneath volcanic arc) is displayed in response much weaker. Except of sensitivity case study, some 3D-distortions analysis was performed. A number of 3D to 2D and 3D to 1D distortions of different MT-transfer functions were evaluated. Obtained results allow to estimate discrepancies due to 2D inversion of 3D MT-data.
