Hydrogeochemical aspects of uranium deposits

The fundamentals are presented of the radiohydrogeological method of the revelation of water aureoles of the scattering of radioactive and accompanying elements with the consideration of specificity of the hypergenic U migration, mitallogeny of the territory, topographic, geological-structural, hydrogeological, geochemical and climatic conditions. Factors are enumerated which influence the enrichment of natural waters with uranium and the development of pseudoanomalies as well as factors which indicate the genetic connection of water anomalies with uranium ores: correlations of the U content of waters with the concentration of solved salts under the condition of the arid climate as well as the correlation of the U content and HCO3 ion. Brief characteristics of the following elements-indicators: Ra, Rn, He, Mo, Cu, Zn, Sb, Pb, As, V, P, isotopes of U, Ra, Th are given. Their complex investigation will make radiohydrogeological research much more efficient
