摘要
According to Sakai-Ohmoto's theory regarding the evolution of sulfur isotope in hydrothermal system, by using new data on chemical reaction equilibrium constants,equilibrium isotopic fractionation factors as well as on individual ion activity coeffidents of sulfur species the following diagrams of lgfo2-pH are constructed: a) Mole fraction of aqueous sulfur species (Xt), b) Stable field for some minerals in Fe-S-O system, c) diagram depicting the rate of oxidation-reduction state of aqueous sulfur species(R'), and d) Isotopic composition of sulfur compounds (δSt^34).
