Аннотация:A new approach to the classification of hydrothermal ore-forming systems was proposed on the basis of the study of individual fluid inclusions. The ratio of the total pressure in a hydrothermal system to the pressure of saturated water vapor at a given temperature (a standard characteristic of open fracture conditions), (P-H2O + P-gases)/P-H2O, was taken as the main classification criterion, which reflects the degree of tectonic isolation. A scheme of classification of hydrothermal ore deposits by chemical composition and physicochemical properties of ore-forming fluid was developed. The limiting parameters of three main types of hydrothermal ore-forming systems were determined from mass and systematic studies of individual fluid inclusions in minerals from 17 hydrothermal ore deposits of different origin. These three types were distinguished on the basis of the aforesaid ratio (in parenthesis): open (1-2), semiclosed (1-20), and closed (1-200) systems.
