Abstract
A three-dimensional resistivity model is presented that contains electrical resistivity anomalies of a complex shape on three structural levels: in the sedimentary cover, in the consolidated crust, and in the upper mantle. The synthetic (model) magnetotelluric data obtained as a result of solving the direct problem are analyzed to identify anomalies associated with resistivity in inhomogeneities at different depths. Quantitative estimates of the sensitivity of various components of the magnetotelluric data to these inhomogeneities are given. Further, we plan to use the presented data to evaluate the efficiency of various methods for solving inverse problems.
