Figs. 8.3, 8.4, and 8.5 for synthetic 3D model, station location, and profile location). Station data is decomposed according to the strike direction of the crust (N45W), and inversion is carried out with resistivity laplacian regularisation and a lower smoothing parameter (τ = 1), following the first inversion approach: isotropic inversion of short-period data in the first sequence and anisotropic inversion of long-period data in the second sequence. 306
