ESTIMATION OF FORMATION CONDITIONS OF MINERAL MEGASYSTEMS FROM THERMODYNAMIC MODELING

Abstract

The temperature and pressure of the formation of mineral assemblages and composition of fluid are currently estimated largely with the method of phase correspondence [1, 2]. This method consists in calculation (on a thermodynamic or experimental basis) of a certain stoichiometric mineral reaction, end member relationship, or a complex of certain reactions that determine the PT parameters and fugacity of volatile components.
