Abstract - Summary 
(short description):
We generalized the results of the principal physico-chemical parameters determinations (temperature, pressure, density, aqueous solution salinity, fluid gaseous composition) characteristic of the natural mineral-forming fluids. These results were obtained from the database including above 17500 reports on fluid and melt inclusions. The data on the occurrence frequency of fluid inclusion homogenization temperature within different temperature intervals were obtained for 21 minerals. This allowed to find out the most favorable temperature ranges for the mineral formation. The frequency occurrence of natural fluid temperature and pressure values in the range of 20-1200oC and 1-12000 bar was established on the base of 5260 determinations. The frequency occurrence of predominantly aqueous and predominantly anhydrous fluid inclusions was calculated. The frequency occurrence of temperature and salinity values of the hydrothermal mineral-forming fluids within the range of 20-1000oC and 0-80 wt. % equiv. NaCl was determined as well as the frequency occurrence of temperatures and fluid densities within the range of 20-1000oC and 0.01-1.90 g/cm3 (18000 determinations). Among the set of various gaseous phase analytical methods used in fluid inclusion studies at 1965-2007 the most abundant ones were separated out. The average composition of natural fluid gaseous phase was calculated by use of mere than 2800 determinations obtainer by Raman spectroscopy, the later being the most abundant analytical method in the study of individual fluid inclusions.
