| Abstract | This paper aims at reporting the 3D modelling criteria for complex crystalline geological setting for geothermal prospection studies. In this study the available data of the Argentera Massif, in the southwestern Alps, have been used to come out with 3D models at different scales using the software 3D Geomodeller by Intrepid Geophysicis which is based on a potential field interpolator. Large scale models helped reconstructing the relationship between major faults, the geometries of the metamorphic formation and of the intrusive granitic bodies in the subsurface. Small scale models were used to better constrain the geological formations and fracture systems related to the thermal fluid circulation at the thermal sites of Bagni di Vinadio and Terme di Valdieri, located on the Italian side of the Massif, where hot waters discharge at temperatures up to 70°C. |
