Resumen:
It was found that the minimum errors associated with the direct use of SiO2 and Na/K geothermometers are within ±8% (SiO2) for temperatures between 137°C-340°C and ±29% (Na/K) for temperatures between 150°C-350°C. Propagation of the analytical errors related to the determination of the ionic components shows that the errors associated with the geothermometers can increase up to ±33% for SiO2 and ±31% for Na/K. Error values higher than those indicated in this study may be related to sampling techniques of the fluids or to the presence of geological-thermodynamic processes present in the geothermal system. -from English summary
