Аннотация:Available fluid inclusion data on hydrothermal deposits, deepseated xenoliths, magmatic and
metamorphic rocks were used to generalize the determinations of physicochemical parameters (temperature, pressure, and compositions) of natural fluids. It was established that fluid pressures during formation of hydrothermal deposits often exceeded lithostatic loading (250–270 bar/km) of the overlying rocks. Fluids from deepseated xenoliths, magmatic and metamorphic objects are considered as the possible sources of highpressure fluids. Data on temperatures, pressures, and fluid composition are generalized for each object.
