The basic pattern of the uranium mineralization's southwest segment of Chenzhou-Qinzhou uranium metallogenic belt

Uranium mineralization types at the southwestern segment of Chenzhou-Qinzhou uranium metallogenic belt is various and complicated. Because the formation time of the mineralization and granite is quite different. The mineralization formed in a narrow time gap which coincides with the faulted down period of the regional extension in Later Yanshanian. Different types of uranium deposit are low temperature hydrothermal uranium deposit which is controlled by the deep great fracture due to the spreading. There are many sources for the uranium mineralization. (author)
