    Abstract

    The Jifei hot spring is a typical travertine-depositing hot spring with many travertine cones. The spring water is meteoric in origin and is heated when it undergoes deep circulation of 1792. m through the well-developed faults. Based on the hydrochemical and isotopic analysis, the estimated residence time of the deep circulating meteoric water is 35-50 years and the estimated reservoir temperature of the thermal groundwater is approximate 110.9. °C. The mixing ratio of the cold groundwater is around 44% in the Jifei hot spring calculated by mass conservation method of enthalpy and silica dioxide concentration. Finally, a conceptual diagram of the genesis of the Jifei hot spring is given. In addition, it has been inferred that the travertine deposited from the beginning of the Holocene Epoch.
