Cl⁻ as a Chemical Fingerprint of Solute Transport in the Aquitard-Aquifer System of the North Jiangsu Coastal Plain, China

Figure 7

Cl⁻ versus (a) Br⁻ concentrations and (b) δ²H of porewaters in the aquitards and groundwater in aquifers. The groundwater samples are referred from Fu [20]. The red line represents the diluted line of standard seawater (SW), and the red dotted line represents SW evaporated trajectory. The paths for evaporating seawater are from Fontes and Matray (1993) [24].
