Hydrochemical evolution of hydrothermal systems driven by seawater mixing in the southeastern coastal region of China: insights from water chemistry and isotopes

Key Points

• Chemical evolution showed distinct variations linked to seawater mixing, influencing hydrothermal systems.
• Key measurements included water chemistry profiles and isotope ratios across various sites during analysis.
• Assessment using chemical and isotopic data clarified hydrothermal interactions influenced by seawater.
• Findings suggest that understanding these systems can enhance models of coastal hydrothermal dynamics.
