Genetic analysis of Hailuogou hotspring

This paper expounds the origin of Hailuogou hotspring in water source,heat source and structure through analyzing the regional geology,hydrogeologic conditions and hydrogeochemical features.The hotspring is recharged by karst and tectonic fissure water which derives from precipitation,meltwater and river water,which flows and cycles deep down to Hailuogou fracture zone and affected zone where the water and "steam distillation" from deep crust with high temperature and pressure are mixed,and at the meantime,some related physical and chemical processes such as heat exchange,ion exchange,lixiviation and adsorption are proceeded.All these factors generate the high temperature mineral water with unique hydrochemical characteristics.The hotspring is found where the tectonic structure and landform are suitable.It has the great value to exploit the geothermal resources and study the geological tourism in Hailuogou.
