| The Application of SiO2 Geothermometer to Estimating Temperature of the Geothermal Reservoir: Exemplified by some Thermal Springs in Henging Area, South Jiangxi |
| This paper deals emphatically with the application of SiO 2 geothermometer to estimating the geothermal reservoir temperature of some thermal springs in Hengjing area. Studies show that, when the dissolved SiO 2 (quartz) enthalpy diagram is used for adiabatic cooling, and the quartz geothermometer equation is adopted for conductive cooling without mixing with cold water during upflow, the lowest estimated temperatures of the geothermal reservoir are in the range of 78～134 ℃ and the highest estimated temperatures are between 95 and 155 ℃. When the dissolved SiO 2 (quartz) enthalpy diagram is employed for the mixing models, in which the steam was lost before mixing with the cold water, the lowest estimated temperatures of the geothermal reservoir are in the range of 83～138 ℃. Therefore, it is believed that the lowest temperatures of the geothermal reservoir in Hengjing area are probably in the range of 78～138 ℃ and the highest temperatures are in the range of 95～155 ℃. |
