Therefore, we will use the Si[O.sub.2](aq)-Q geothermometer and, specifically, the calibration proposed by Fournier (1977) due to the similarity of the rest of existing calibrates; ii) Geothermometries based on the Na/K ratio: Empirical calibration proposed by Ellis (1970) or Anorsson (1983), theoretical calibration calculated from thermodynamic data for albite and K-feldspar proposed by Michard (1983) and empirical calibration proposed by Michard (1990), since give the more consistent results with the proposed temperature by the geothermometers based on the dissolved silica; iii) Geothermometry based on the Na-K-Ca relation: Empirical calibration proposed by Fournier and Truesdell (1973).

Chemical Geothermometer. Chemical geothermometers were applied to estimate the temperatures of the geothermal reservoirs, including a silica geothermometer (the solubility of silica changes as a function of temperature and pressure) and a cation geothermometer (the equilibrium constants for exchange and alteration reactions are temperature-dependent).
