| Popis: | We studied by physicochemical modeling (PCM) how the temperature and redox properties of the crystallization atmosphere affect the equilibrium compositions of product phases using trachyandesibasalt as an example. The chemical composition of rock-forming minerals and their influence on the properties of rocks are presented. The heating, melting, and crystallization features of trachyandesibasalt are considered taking into account external conditions and the mutual influence of the minerals present in the rock. Temperature-dependent magnetization is determined for various fractions of the studied rock. The fundamental possibility is shown, and recommendations are given, for choosing methods to modify the chemical and mineral composition of trachyandesibasalt. |
