Abstract:: In this study,10 groundwater samples were collected in the Eastern Piedmont Fault of the Helan Mountains to investigate the hydrogeochemical characteristics during the flood and dry season by various methods,such as Piper trilinear diagrams and ion ratios.We also discussed how the Eastern Piedmont Fault of the Helan Mountains was related with the chemical composition of the groundwater and the earthquake activity. We further built a model illustrating the genesis of the groundwater in this area.The results show that:① The groundwater is generally alkaline in this area.The main cations in groundwater samples are Ca²⁺and Na⁺,while the main anions are HCO^-₃ and SO^2-₄.② Hydrogen and oxygen isotopes indicate that precipitation is the main source of recharge for groundwater in the study area,and the recharge height is between 1.07 km and 2.04 km.Almost all groundwater in the study area is “immature water” with a weak degree of water-rock reaction.The mineral saturation index in most water samples is less than 0,indicating that the content of each ion in the regional groundwater is generally in an unsaturated state.The geothermal reservoir temperature calculated is 74.6 ℃—114.1 ℃,and the circulation depth ranges from 1.8 km to 2.7 km.③ Most of the trace elements enrichment factors(EF)are less than 1,indicating that the groundwater is “immature”with low mineralization.The degree of water-rock reaction was relatively weak.④ Water temperature,mineralization,mineral saturation index and water circulation depth is high in the north part and low in the south part.The small earthquakes's activity has a high frequency but weak intensity in high value zone of hydrochemical components.⑤ Groundwater in the study area is recharged by infiltration of atmospheric precipitation in the nearby mountains,and the groundwater during subsurface circulation is heated by the Earth's heat flow.The groundwater reacts with the surrounding rock and eventually rises along the fracture to the surface as hot springs.
