Geochemical Study of Groundwater Mineralization in Guanzhong Basin, Shaanxi province, NW China

摘要

The object of this study is to determine the main geochemical processes that affect the formation and quality of the Guanzhong Basin. As the chemical characteristics presenting a large spatial variability, the study area is sampled in different zone and different depth respectively. Based on chemical analysis, the main water chemical actions are the decarbonation and desulfurization function, dissolution. Decarbonation function is happened widely in Guanzhong basin while Desulfurization fanetion is only found in deep stratum of Xi'an. Dissolution of calcite results in the Ca-HCO3 type water of mountainfront recharge area.
