High- and Low-Temperature Hydrogeochemical Processes and their Control on Water Composition in the Domuyo Geothermal System

Key Points

• Water composition varies drastically with temperature changes, highlighting the role of hydrogeochemical processes in geothermal systems.
• Observations showed that mineral interactions contribute significantly to the variations in water chemistry across temperatures.
• Analysis of geothermal water samples indicated distinct hydrogeochemical processes at high and low temperatures, affecting mineral solubility.
• Understanding these processes can help improve geothermal resource management and environmental assessments in similar regions.
