| Abstract | Geothermal heat flow anomalies are often linked to graben structures at the top of the crystalline basement. Numerical thermo-hydraulic models have attributed a strong contribution to fluid flow in the fault zones building up the rim of these through structures. It is, however, a challenge to identify such or any other structures in the crystalline basement. In this paper, we present a 3D geological model based forward modelling employing finite element modelling and a detailed analysis of high- and bandpass Butterworth filters to assess the location and geometry of different geothermally relevant structures in the crystalline basement in Switzerland and elsewhere |
