Isotope constraints on the hydraulic relationship of ground-waters between Quaternary and Tertiary aquifer in Xi'an area; Shaanxi province

Isotope techniques are increasingly used in evaluating the hydraulic connections between groundwaters in different aquifers, and can improve the geological and hydrogeological database. In the Xi'an area, the upper Quaternary aquifer may have hydraulic connection with the lower aquifer, the Ter...

Description
Summary:Isotope techniques are increasingly used in evaluating the hydraulic connections between groundwaters in different aquifers, and can improve the geological and hydrogeological database. In the Xi'an area, the upper Quaternary aquifer may have hydraulic connection with the lower aquifer, the Tertiary aquifer, based on geological analyses. δ2H, δ18O,3H, and14C data of groundwater samples provide further evidence for the existence of the hydraulic connection between both aquifers.
