Faculty of the finance and credit popup.description2 Objects of research: mineral units and mineral paragenesises of gold-polymetallic and gold deposits of Ukraine. Methods of research - mineralogical mapping, ontogenetic researches of mineral individuals and units, optical microscopy, the X-ray-spectral microprobe analysis, the X-ray-phase analysis, methods of the researches of physical properties of minerals. Complex mineralogical-geochemical researches are lead {carried out} for restoration of a structure of zones of geochemical barriers and reconstruction of dynamics {changes} of accumulation of minerals in their borders by the example of the basic gold-main objects of Ukraine - Muzhiyevo, Beregovo and Mayske deposits. We have studied ontogenesis of the minerals of silver in polymetallic ores of the Muzhiyevo deposit, age and spatial parities {ratio} their mineral paragenesises, have established parameters mineral-forming solutions. We reconstructed the basic features of evolution of Beregovo epithermal systems with the help of physical and chemical modeling; and also have studied the mechanism of functioning the galena barrier accumulation of silver in ores epithermal deposits, have established mineralogical ash value which is formed on such barrier. A number of prospecting-estimated criteria for mineralized zones of Inner-Carpathian of a volcanic belt has been offered. Results of researches can be used in regional geological manufactures. The developed techniques mineralogical mapping and genetic modeling can be used for a tentative estimation of new sites on the researched areas with a hydrothermal mineralization.
