| 摘 要： | 文章利用纹理增强技术对松辽盆地南部通辽地区的DEM进行增强,并运用增强结果对该区线性构造进行解译。通过将遥感影像和DEM纹理增强图像进行综合,成功识别了乌兰浩特-扎赉特旗-龙江县一线的生长断裂和双辽地区的后生断裂,再通过将已知铀矿(化)点叠置于构造解译图上,发现铀矿(化)点与双辽后生断裂在空间上具有相关性,说明双辽后生断裂极可能是一条控制铀矿形成的断裂,也说明将DEM纹理增强图像同遥感影像结合可为覆盖区构造解译和铀成矿要素的识别提供新的思路和技术支持。

| Abstract: | In this paper,the texture enhancement technique was used to enhance the DEM of the Tongliao area in the southern Songliao Basin,and the fault was interpreted using the enhanced results.By compositing the remote sensing images and texture-enhanced DEM,the growth faults running throng Wulanhaote-Jalaid Banner-Longjiang County and the post-sedimentation faults of Shuangliao area were successfully identified.By superimposing the known uranium deposits on the structural interpretation map,it is found that the uranium deposit is spatially related to the Shuangliao fault,indicating that the Shuangliao fault maybe control the uranium formation.The combination of texture-enhanced DEM with the remote sensing image may provide new ideas for the geological interpretation of the coverage area and the identification of uranium metallogenic elements. |
