Abstract

We provide new thermodynamic and kinetic data concerning the dissolution and precipitation of silica in hot and superhot geothermal systems. Different methods were applied, including traditional photometric methods and in situ Raman and conductimetric methods. The studies covered the interactions of silica with both pure water and saline solutions. The kinetics of silica polymerisation were studied in the presence of various metal ions and at different pH values, informed by an analysis of real geothermal water samples from the Tuzla region of Türkiye.
