Abstract:
luid-mineral equilibria, suggesting that the corresponding reservoir should be at less than 2 km depth. In
a geothermal reservoir, the groundwater is heated by heat flow and incongruently dissolves the subsurface
minerals and emerges in the form of hot springs along fault and fracture conduits. During their ascent to
the surface, they are subjected to various physical and chemical changes such as cooling by conduction
and change in their chemical constituents due to the mixing with cold groundwaters, which are clearly
indicated in silica and chloride enthalpy mixing diagrams.
