Convergence of the TM inversion is significantly improved if vertical conductive
channels crossing the high-resistivity lithosphere are introduced into the starting
model. Figure 12.36 shows the result of such inversion. Here, we have a model
with three vertical conductive channels associated with the Obruchevsky, Barguzin,
