| 摘 要： | 中亚天山造山带中央克兹勒库姆铀成矿区是世界驰名的铀矿产地,区域构造上属叠加于海西期地槽褶皱造山带上的喜马拉雅期活化造山带中的次级造山带,有大量层间氧化带砂岩型和碳硅质板岩型铀矿床分布。经活化构造成矿分析,铀成矿作用经历了多个大地构造演化阶段,地槽造山阶段形成铀源层、体,地台阶段形成部分有利铀成矿和储矿的砂岩层,活化造山阶段形成淋积和热流体成因的工业铀矿床。

| Abstract: | Central Kyzylkum uranium region is famous for its large quantities of interlayer oxidation sandstone type and carbonacous-siliceous slate type uranium deposits.In tectonics,this area belongs to sub-orogenic belt of Himalayan activiation which superimposed on the folded Hercynian geosincline.From the point of metallogenic analysis of tectonic activation,uranium mineralization in this region has experienced several geotectonic evolutionary stages： uranium source layers and bodies were formed in geosynclinal stage,favorable ore hosting rocks and metallogenic space were formed in the stage of platform,and economic mineralization of infilterational and hydrothermal genesis has been formed in activation stage. |
