Fig. 13

Images of the subsurface obtained by inverting the four computed TE apparent resistivity pseudo-sections shown in Figs. 5, 6, 7 and 8. These images are in the same order as those in Fig. 10. a and c are for the two fixed angles and b and d for the related invariants. The inversion was performed using the 1D formula of Eq. 10 for harmonic averages of resistivity between two depths \(h_{2} \;{\text{and}}\;h_{1}\). The dots correspond to the geometric mean \(h_{m} = \sqrt {h_{1} h_{2} }\)
