Abstract
Complex of the searching-valuation criterions of the Rakhiv ore region gold mineralization have been elaborated. The main amongst them are mineralogy-genetic, geology-structural, thermobarogeochemical and mineralogy-physical ones. The main favorable criteria for gold are: the spread of productive mineral associations and syngeneic fluid inclusions with them; carbon dioxide-water composition of mineral-forming fluids, inclusions in minerals, the density of which does not exceed 0.5 g/cm3; medium temperature conditions of mineral formation (280–120 °С); distribution and sequence (from {100} + {210} to {210}) of crystallization of combined forms of pyrite, which are characterized by: mainly np- and p-conductivity and numerical vectors (in the coordinate system RV – average), oriented towards higher values hole conductivity; the presence of galena, the value of thermoelectric force which is more than 800 μV/deg. Based on the developed criteria, we offered a number of specific recommendations on the prospects of the studied ore occurrences, Saulyak deposit and Rakhiv gold ore district in general.
