Аннотация:The accurate calculation of an infiltrational metasomatic column is still among the most difficult problems of the thermodynamic simulation of hydrothermal processes. Two major approaches to this problem exist. One approach exploits the equations of the dynamics and kinetics of the processes involved in metasomatism. The second involves the equilibrium simulation of interactions in the rock-water system. The second approach is advantageous in that it easily adapts to a system of arbitrary complexity given that programs for chemical equilibria calculations exist far this system. This paper discusses the possibilities of equilibrium simulation as applied to study infiltration metasomatism. The equilibrium approach is exemplified by the algorithm that computes an isobaric-isothermal infiltration metasomatic column with a high accuracy and efficiency.
