| Abstract | Dālaki Geothermal Resource (DGR) is located 70 km to the northeast of Bushehr city. There is only one warm spring in DGR which its temperature is 36 ºC and its flowrate and pH is 18 l/s and 6.4 respectively. DGR is believed that relates to a salt dome. Due to the presence of salt and gypsum bearing rocks in the DGR, Cl and SO4 ions concentration of Dālaki warm spring are very high. Based on geothermometery studies Dālaki geothermal reservoir temperature is from 66 to 146 ºC. Probably DGR heat source is normal thermal heat flow of the region. In fact, uprising of salt bodies provides high angle faults which allow rainfall waters penetrate to deeper parts of the region, absorb heat from nearby rocks and finally forming a geothermal reservoir in the region. |
