STRUCTURAL FACTORS FOR SEARCH OF EXOGENOUS URANIUM DEPOSITS

Романов А.М.
Formation of exogenous deposits of uranium is connected with the zones of oxidation and reduction. Specific change notes for mineral composition of the ore rocks. The actual distribution of minerals is not consistent with accepted models of formation uranium mineralization in exogenous conditions. Redox capacity of ore bearing rocks is not explained by the presence of increased contents of minerals with high values of redox potential. But structural factor – distribution of ore mineralization sites to change the cross section of water supply aquifers – necessarily peculiar on the exogenous deposits of uranium. Speed of the water flow changing in these places. Consequently changes the natural tension of electric field potentials of the flow. Electric field effect on the cations of solutions and determines the interaction of the solid and liquid phases. Characteristic distribution of the ore and rock-forming minerals consistently explained features uranium deposits. Structural factor – changing of the cross-section of water supply aquifers – is proposed to use for searching exogenous deposits of uranium. The change cross-section can register of electrical prospecting by the method of vertical electrical sounding. Availability of increased intensity of interphase exchange can register by the positive anomalies of the method of the natural electrical fields.
