Fig. 4: Mixing between seawater and geothermal groundwater.

a Cl− against Na+. b Cl− against DSi. c Cl− against Mg2+. d Cl− against Ca2+. Data for thermal fluid (square), fjord water (star), and meteoric water (triangle) from the Aysén region reported by Negri et al. (ref. 13) are shown in black; averages for each subgroup are shown in red. In all plots, mixing lines between geothermal groundwater and seawater (black diamonds) are shown, with gray windows highlighting the range of potential mixing lines derived from the minimum and maximum (95% confidence interval) endmember estimates.
