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.
