| Abstract: | The basic regional geologic tectonic framework and the evolution of Shamai area are introduced in this paper,and two (NE and NNE trending) tectonic belts are recognized in the study region.It is suggested that Meso Cenozoic basins in the region are originated from the NWW SEE extension.The relation of tectonic evolution to sandstone type uranium mineralization is discussed in this paper as well. |
