8. Recovering a synthetic 3D subsurface model using lower-dimensional inversion schemes Fig. 8.19.: Results of anisotropic 2D inversion of the synthetic 3D model for a selection of profiles, from left to right: 3D-crust-west with stations synM11 – synC01, 3D-crust-NS with stations synE02 – synL09, and 3D-crust-east with stations synN10 – synD00, as well as 3D-crust-EW profile with stations synD10 – synM01 (upper most plot); see Figures 8.4 and 8.5 for location of stations and profiles. Results are plotted in respect to the station locations; see black lines in the inset on the top-right of the figure. The solid black line in the main plot indicates the projected location of the 3D-crust-EW profile result (model shown on the top of this Figure), and red inverted triangles on the 3D-crust-EW profile denote location of intersection by the other profiles. Dashed lines indicate resistivity interfaces of the synthetic 3D model at crust (red) and mantle (blue) depth (cf. Fig. 8.3). For orientation, side panels are shown, which indicate regions of the synthetic 3D model by colour, following the colouring of the synthetic model. More detailed inversion results for the four profiles are given in Section A.3.2 (Figs. A.15 - A.18). 198 synN10 synM11 1.60 synM05 synL09 synL04 1.60 ynK08 2.35 synK03 1.98 synJ07 syn J02 synH10 synI06 3.10 synI01 2.35 synG09 synF08 1.60 synH05 synG04 3.85 2.73 synE07 2.05 synF03 synD06 synE02 Log10(Wm) 4.60 synD00 3.10 Log 10(Wm) 2.50 2.95 synC01 Log10(Wm) 3.40 250 300 1.60 Depth (km) 150 200 Log 10(Wm) 1.98 2.35 0 50 100 2.73 3.10 W E synD10 synE09 synF08 synG07 synH06 synI05 synJ04 synK03 synL02 synM01 N N
