There is a discription of dynamical physical and chemical model of “flow reactor with an ideal piston displacement” type. With its help using the SELECTOR program complex (PC) for thermal solutions of Golovnin caldera (Kunashir Island, Kuril Islands) the numerical experiments were performed. The results of two “water-rock” type (W/R) systems modeling are represented: 1 – thermal solutions with pH=1.93; 2 – thermal ones with pH=6.35. The temperature range from 200 to 15 °C and the pressure of 1 and 10 bar in both experiments were used. As a results, data on the systems phase and chemical compositions were obtained; an evolutionary sequence of physical and chemical system states was identified with long-term water/rock (W/R) interaction; a metasomatism type for systems was gained; a metasomatic column was verified with ones near the orifice of thermal solutions. Thus, the complete correlation of model data with obtained in situ one was shown.
