Аннотация:Abstract—This paper continues a series of our earlier publications summarizing literature data on the physicochemical parameters and chemical composition of fluids at endogenic gold deposits and presents estimated average values of the temperature, pressure, and salinity of fluids, and variations in these parameters, at Mesozoic gold deposits. Parameters of mineralizing fluids at the Mesozoic deposits are discussed in comparison with the analogous parameters of fluids at Archean, Proterozoic, and Paleozoic gold deposits. The Mesozoic deposits are determined to generally differ from the older deposits in having fluids of higher temperature and lower pressure, with carbon dioxide in these fluids dominating over other gases.
