The translation method predicted phase equilibria on geometric images of the system K,Mg,Ca||SO4,Cl-H2O at 00 C. It was found that at 0 °C the studied system is characterized by the presence of 6 invariant points, 18 monovariant curves and 15 divariant fields. Based on the data obtained, a diagram of the phase complex of the K,Mg,Ca||SO4,Cl-H2O at 0°C and fragmented by divariant fields, as well as crystallization fields of individual equilibrium solid phases, was constructed.
