The decrease in fluid pressure from ancient gold deposits to younger ones may be associated with differences in the erosion depths of ancient and young mineralizing systems. Cenozoic gold deposits generally differ from older gold deposits in having a higher fluid temperature and salinity, lower pressure, and the highest value of the CO 2/CH 4 ratio. The chemical composition and parameters of mineral-forming fluids of gold deposits were determined to systematically evolve with time. Parameters of mineralizing fluids at Cenozoic gold deposits are discussed in comparison with the analogous parameters of fluids at Archean, Proterozoic, Paleozoic and Mesozoic gold deposits.

The inherent features of the gas composition of the mineralizing fluids of these deposits are revealed. NaCl) of fluids of Cenozoic gold deposits are estimated. The average values and variation limits of the temperature (50–845°С, mean 290☌), pressure (20–3600 bar, mean 600 bar), and salinity (0.1–88.0 wt % equiv. The paper completes our summary of literature data on the physicochemical parameters and characteristics of the chemical composition of mineralizing fluids at endogenous gold deposits.
