Discussion on the crustal evolution and uranium mineralization of the Xikang-Yunnan Axis

According to the regional metallogenetic regularity of various types of the uranium deposits, the recognition of the uranium metallogenetic prospective model in an unknown area is summarized and uranium mineralization in the evolution process of the earth's crust of the Xikang-Yunnan Axis is analysed. The author points out that uranium mineralization had not developed before the Jinning Movement, but it was developed during Chengjiang period, Hercynian period and Indochina-Yanshanian period, respectively, among them, uranium mineralization during Chengjiang period was much more important
