Abstract

Numerical simulations of water-rock systems based on D.S. Korzhinskii’s hypothesis of the openness-closedness of natural systems indicates that the composition of groundwaters evolves into Cl-Na-Ca brines at increasing R/W ratios (rations of reacting rock and water masses) and when the system becomes closed (a decrease in the CO2 partial pressure) or into HCO3-Cl-Na brines at a decrease in the R/W ratio and the opening of the system with respect to CO2 (increase of P CO 2).
