Supercritical Fluid Geochemistry in Geothermal Systems

Figure 7

The concentration of subcritical and supercritical geothermal fluids observed in the experiments and at Krafla, Iceland [31, 41]. Also shown are predicted equilibrium concentrations assuming mineral-fluid equilibria at subcritical conditions [41, 47] as well as quartz and salt equilibrium solubility concentrations in supercritical water [44–46].
