| Title | Hydrogeology key role in a geothermal exploration in southern Italy |
| Abstract | Several "target areas" (each one of 20 km2 ) were selected in Southern Italy for geothermal exploration in the frame of Ministry of Economic Development (MISE) and National Research Council (CNR) joint project: Evaluation of Geothermal Potential in Convergence Regions, (VIGOR) founded by POI Programme 2007-2013.
In Campania region a selected area is located between the Mondragone town and the southwestern side of Mt Massico, an horst structure constituted by carbonate and terrigenous sediments.
In the selected area there are two thermal springs Sinuessae (SN) known since roman time and "S. Maria dell' Incaldana" (SMI). The characteristic of the two springs are for the first one a discharge of 1-2 L/sec and a T of ~ 54°C and for the second one a low discharge increased by wells until 10 L/s, and T of ~ 33 °C
The hydrogeochemical analysis of SN and SMI springs show differences in salt concentration, gas and isotope content, which allows to hypothesize different marine influence and hydrographic system.
The origin of these two thermal springs is probably related to faults as a preferential pathway for fluid and gas, like in other geothermal areas of southern Italy.
The VIGOR geothermal exploration includes detailed geological and geophysical surveys, hydrogeological investigations and explorative wells.
Peculiarly, deep hydrogeological investigations (hydrochemical and isotopic characteristics of groundwater plain and its piezometric pattern, permeability features of the springs area and quantification of groundwater resources) have been developed in order to find the most suitable area to drill a geothermal well. |
