The uranium-bearing granites in South China can be classified into two types, namely, syntectic type and transformation type. A fairly systematic hydrogen, oxygen, carbon, sulfur isotopic study of uranium deposits related to these two types of granit

Uranium bearing hydrothermal solutions during the stage of ore deposition are weakly alkaline and of the Ca2+ - Na+ /HCO3− - F− type. UO2(CO3)22− and UO2F4−, are dominant in the hydrothermal solutions with respect to their activity. Wall-rock

Rb-Sr and U-Pb isotopic studies of the two contrasting granite types of the Daguzhai and Luobuli massifs in South China provide new constraints on the interpretation of isotopic age data for plutonic igneous rocks. A Rb-Sr internal isochron age of 14
