Dynamics of Uranium Ore Formation in the Basement and Frame of the Streltsovskaya Caldera

Full text: Spatiotemporal pattern of uranium mineralization formation in the basement and frame of the Streltsovskaya caldera is generalized on the basis of previous and newly received geological, geophysical, palaeogeodynamics, mineralogical, geochemical, isotope, and geochronological data. Main occasions for uranium minerogenesis in the context of tectonomagmatic cycles (Proterozoic, Caledonian, Variscan, and Late Mesozoic) of the territory evolution and activation of fluid-conducting fault zone network on the basis of seismic cycle model for fluid-saturated rock massifs of the upper seismogenic crust are distinguished. Directions for further investigation and areas, that are perspective for prospecting works on identification of uranium mineralization in the basement and frame of the caldera are determined. (author)
