基于遥感信息延伸研究的DS铀矿床区域地质背景分析

Analyzing regional geological setting of DS uranium deposit based on the extensional research of remote sensing information

先从遥感图像分析中发现鄂尔多斯盆地北部东胜—杭锦旗地区铀成矿区域地质环境为一个由断隆构造、南缘断裂、环形构造等组成的特殊地质环境,然后利用信息集成技术,将遥感信息与地球物理、地质等地学信息相复合,对断隆构造、南缘断裂和环形构造进行了延伸研究,并从区域铀成矿角度对其进行了分析,认为上述特殊的区域地质背景对DS铀矿床的产出具有重要的作用。

Through analyzing remote sensing image, a special geological environment for uranium ore-formation in Dongsheng-Hangjinqi area consisting of fault-uplift, southern margin fault and annular structure is discovered in this paper. Then the extensional researches on fault-uplift, southern margin fault as well as annular structure are made by using the information-integrated technologies to overlap the remote sensing information with other geoscientific information such as geophysics, geology and so on. Finally, the unusual regional geological setting is analyzed in the view of uranium ore formation, and its influences on the occurrence of DS uranium deposit are also discussed.
