Geothermal energy possibilities of the Banaz Hamambogazi Area, Turkey
The Hamambo(g)azi spa in western Turkey was built around natural hot springs with T =30-44 ℃.Thermal water with a temperature of 62-73 ℃ is now produced at 125 L/s from 4 drilled since 1994, causing some springs to go dry. A management plan is needed to maximize the benefits of this resource, for which currently proposed uses include district heating and green houses as well as in new spas in the area. The best use for the water from each spring or well will depend on its temperature, chemistry and location. The thermal waters are Na-Mg-HCO3-SO4 fluids that contain a significant amount of CO2 gas. Isotope results (18O, 2H, 3H)indicate that thermal waters have a meteoric origin: rainwater percolates downward along fractures and faults, is heated at depth, and then rises to the surface along fractures and faults which act as hydrothermal conduit. The basement around the Banaz Hamambo(g)azi resort is comprised by the Paleozoic metamorphic schist and marbles exposing 8 km south and 15 km north of Banaz. Mesozoic marble, limestone and ophiolitic complex are observed a few km west and northern part of Banaz. These units were cut a depth of 350-400 m in boreholes drilled by MTA. In the area, lacustrine deposits are composed of fine clastic units which are alternated by gypsum, tuff and tuffites of 200-350 m thickness. The marble and limestones comprise the hotwater aquifer while lacustrine deposits make up the impermeable cap.
