Abstract
The sodium bicarbonate waters of Kizildere geothermal system are close to equilibrium with hydrothermal minerals at 220°C and Pco2 of 30-50 atm. The main upflow zone of these deep waters I probably north of the geothermal field, where they undergo a limited steam separation. Then they infiltrate at shallow levels moving southward and mixing progressively with shallow waters. Both the chemical features of the sodium bicarbonate thermal end member involved in the feeding of the other main surface manifestations (Tekke, Haman, Kokar Haman, Demirtaas and Golemez) and the thermodynamic conditions at depth under these sites are very similar to those of Kizildere. Hence it seems likely that a unique sodium bicarbonate thermal water feeds all these sites.
