Mixing, conductive cooling and CO2 input in the geothermal system of Caldas de Boí(Central Pyrenees, Spain): Effects on pH
The Caldas de Boí geothermal system is associated with the granitic rocks of La Maladeta massif, located in the Axial Zone of the Pyrenees (North-east Spain). The dense fracture network affecting the pluton has enhanced the development of the geothermal system, acting as the main water flow paths. Thermal waters in the Caldas de Boísystem are included in the geochemical group of the thermal alkaline waters, and are similar to many other thermal waters associated with granitic massifs in the Pyrenees. However, differences in pH values and temperature of the thermal waters have been reported, indicating that they are affected by secondary processes like mixing with superficial waters, conductive cooling of different intensity, and atmo spheric/edaphic CO2 input. The effects of these secondary processes have been investigated, first by studying the variations in the chemical contents, and second by studying the evolution of some other parameters like temperature and pH.
