Resumen: The interest in hydrothermal systems with CO2-rich waters has raised significantly in the last decades, due to their potential as natural analogues for the geological storage of CO2, especially with respect to the possible leakage processes during the storage (e.g. Pauwels et al., 2007). The Lanjarón hydrothermal system, one of these CO2-rich water systems, is located in the Internal Areas of the Baetic System in Sierra Nevada (Granada) and the origin of this CO2 is mostly endogenous and related to active seismic zones (Cerón and Pulido-Bosch, 1996). The deep reservoir of this carbonic system can be considered a good analogue for studying the conditions and the possible processes in the deep storage of CO2, and with that aim, a geothermometrical study of this system is presented in this work. Classical geothermometers and geothermometrical modelling have been applied in order to quantify the conditions of temperature, pH and mineral equilibrium in the deep reservoir, as well as the processes that affect these parameters during the ascent of the thermal waters to the springs.
