On the origin and evolution of geothermal fluids in the Patuha Geothermal Field, Indonesia based on geochemical and stable isotope data

Volcano-hosted, vapor-dominated geothermal systems have great potential for power generation, although to date, such systems discovered globally remain limited in number. Understanding of the physical and chemical properties of geothermal fluids (water and gas) in vapor-dominated systems is critical for the sustainable development of geothermal resources. This study aims to clarify the origins, water–rock interactions, and chemical evolution of...
