Uranium Provinces of the World

The paper is a new generalization that covers all the variety of known uranium and complex deposits and almost all significant ore areas classified as provinces and districts (more than 100). Systematization of uranium targets and areas (their typification and petrologic and genetic grouping) is made with new accents: geodynamic and/or hydrodynamic settings of ore location reflected in alterations in host rocks are of major importance for ore deposits, and a controlling factor for ore areas is their relation to typomorphic crustal structures (arcogenic, taphrogenic, orogenic, epeirogenic) and derivatives of their different activation of various ages. Brief stylized characteristics for uranium areas within the established overgroups are given on geohistorical basis using results of original paleotectonic and palinspastic reconstructions. System analysis of extensive factual material allows interregional and intercontinental comparisons, extrapolations and analogies, more precise definition of known and identification of new patterns and predictive criteria and, ultimately, drawing conclusions about polychronous character of the formation of most of uranium provinces, their polytype character and, as a result, their stage-by-stage character with variations in major ore concentrations.
Key words: metallogeny, dome structures, uranium deposits, provinces.
