摘　　要：贵州省中晚二叠世玄武岩位于峨眉山地幔热柱构造东部边缘,属于高镁、高钛玄武岩。省内中西部热液铀成矿,黔中、黔北中二叠系茅口组中上部分布的铀矿点、矿化点、白马洞铀矿床与之有关。深部地幔流体提供热动力条件及部分铀源。Mid- late Permian basalt of Guizhou province is situated in the east border of Emei mountain mantle plume, belong to the basalt of high magnesium and titanium. The hydrothermal mineralization in the middle and westem Guizhou, the uranium ore occurrence, mineralized spot and Baimadong uranium deposit which distributed in the up and middle position of Maokou formation of middle Permian in middle and north Guizhou has relation with it. The deep mantle fluid supplies the thermodynamic condition and some uranium source.
