significant geothermal energy source field. The analysis of power spectrum,

conventional heat flow and silica heat flow methods were implemented to

identify the geothermal waters circulation depth, depth to Curie point and surface

heat flow rate in the Hüdai-Sandıklı geothermal field. Hydrogeochemical facies of

geothermal immature ancient waters having deep circulation in lower hydraulic

conductive aquifers are Na–Ca–HCO3–SO4 and Na–Ca–SO4–HCO3, which is

represented very high ion content because of extensive contact with rocks. The heat

conduction law is employed to specify the rate of heat flow using the geothermal

gradient value. The numerical results determined from silica geothermometer

method, the mean heat flow density and Curie temperature depth are obtained as

103:69mWm2 and 11.81 km, respectively. The study region was represented by a

mean geothermal gradient of 49.18 °C km−1 yielding average reservoir depths of

0.90 km. The estimated Curie temperature, heat flow, reservoir temperature values

demonstrated that the region indicates significant geothermal energy potential

because of the partial melting of lithospheric crust.
