| Abstract | The work carried out in Kosario de la Frontera geothermal area consisted of geologic mapping, construction of stratal lengths and excess area controls, structural balanced cross sections and water sampling of thermal springs for geochemical analysis. structural cross section and the permeabilities of the different geological units, suggest a hydrologic circulation cycle, a recharge zone, the Seco Formation as the main aquifer, and a maximun depth of 3000 m. A source temperature ranging from 90?C to 130?C was obtained from the K-Mg and geothermometers. Geochemical analysis indicates different proportions of mixing with shallow waters and low enthalpy origin for all the hot water samples |
