DISCUSSION ON THE CRUSTAL EVOLUTION AND URANIUM MINERALIZATION OF THE XIKANG-YUNNAN AXIS

In this paper, according to the regional metaltogenetic 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 evolutional 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, Hereynian period and Indochina-Yanshanian period, respectively, among them, uranium mineralization during Chengjiang period was much more important,
