Valles Half-Graben (NE Spain), a Preliminary Regional Geothermal Model

Summary The Valles basin is located in the NE area of the Iberian Peninsula. In this area, some sources of thermal water are known and used since ancient times. These upwellings indicate that there are hot waters at a certain depth, and maybe, that could be exploited. Not much depth geological information is avalaibe in this area but the hydraulic regime sems controlled by the tectonic configuration and the sedimentary material in the subsurface develops aquifers capable to redistribute fluids, solutes and heat. This preliminary study tries to deduce the possible origin of these waters and the comparison with other similar better known areas.
