Ore metamorphism of sulfide deposits of the Urals is written by distinguisting of bornite, chalcopyrite and pyrrhotite facies. With a help of mineralogical geothermometers ranges of their stability by temperature and sulphur fugacity values have been defined. On an example of gold and gold tellurides it has been shown that distinguished facies including measures of temperature and fugacity of sulphur and tellurium permit to make a prognosis of mineral forms of admixture components in ores.
