Water Circulation of Geothermal System in Kaifeng Depression

Abstract Kaifeng is rich in geothermal resources. It is important to clarify its genetic model for its further sustainable utilization. In this paper, the geothermal geological conditions of Kaifeng Depression are analyzed, the circulation of geothermal water in Kaifeng area are discussed by using hydrochemical and isotopic data, and the conceptual model of geothermal system is preliminarily established.
