Hydrogeochemical Evolution of Groundwater in the Dusit-Yanchi Watery System, North of the Ordos Basin

摘要

With the development of energy base in Ordos basin, the deficiency of groundwater becomes serious. Therefore, the hydrogeochemical evolution of groundwater is studied, which is in the Dusit-Yanchi watery system. Some results are obtained. The quality of groundwater in Dusit river system is better, and in the aquifer, the main water-rock action is the solution of gypsum, fluorite, and siderite, and the precipitation of calcite and dolomite.
