Computational Mathematics and Modeling Aims and scope Submit manuscript

We consider a new model of excitation of crustal anomalies that relies on the conjecture of the existence of a weakly conducting layer in the bottom part of the crust. In line with this conjecture, deep fractures may occur in arbitrary positions relative to the conducting anomaly. The model is investigated in the film approximation. We show that magnetotelluric sounding produce a lower biased value for the integral conductivity of the deep anomaly.
