摘要
本文介绍了沙麦地区区域地质构造基本格架及区域地质构造演化 ,划分了区内北东向及北北东向两个构造带 ,认为区内中新生代盆地是地壳呈北西西 南东东向伸展的结果 ,探讨了构造与砂岩型铀矿的关系。
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.
