Fig. 8

Misfit profiles between modelled and synthetic gravity anomalies, considering different density models. a The topographic profile along the reference model line (blue line), together with the projected gravity data points at the surface (orange points). These points have been used to sample the topographic profile and compute the cross-correlation between topography and misfit. b Point-wise misfit for the surface gravity data points, for each of the tested density models (see colour legend), as described in Sect. 2.2. Black thin lines in the lower part of the figure, indicate the location of the geological unit boundaries at the surface, along the profile. The point-wise misfit represented in the figure is defined as synthetic minus observed gravity value. c Same as b for the tunnel points
