has been performed using the
smoothing REBOCC program; A, B, and C are conductive zones in the crust (cf. Fig. 12.16)
three hypotheses concerning the position of the crustal conductive layer: (1) a con-
ductive layer overlies the seismic waveguide (25-35 km), (2) a conductive layer
coincides with the seismic waveguide (35-50 km), (3) a conductive layer underlies
the seismic waveguide (50-70 km). The interpretation model has been constructed
in line with the second hypothesis, which resulted in the minimum model misfit. It
consists of 70 blocks of a fixed geometry (Fig. 12.19). The partition density depends
on the position and size of supposed structures and is highest within the sedimentary
cover, local crustal conductors, and crustal conductive layer. The model allows for
