Concentration of Cl plotted versus concentrations of conservative elements Na, Mg, and Sr with best-fit linear regression lines. The large filled symbols at high Cl concentration represent seawater [32], while the filled circle at low Cl concentration represents the average Na concentration in two collected rainwater samples [13]. All concentrations are log10 values in mg/L
