| 中文摘要: |
| 在西部高寒山区开展地质矿产调查工作难度较大,遥感技术可以发挥先导性作用。研究工作采用ETM卫星遥感数据,通过多种遥感图像处理,在建立各地质体解译标志的基础上,对地层、岩浆岩和构造等重新厘定和详细解译,编制了1∶5万遥感地质解译图,发现了两处色调异常区,同时还提取了与金属矿化有关的蚀变信息,为地质矿产调查提供了新的基础资料和找矿目标地,取得了良好的应用效果。 |
| 英文摘要: |
| It is difficult to carry out geology and mineral resources survey in western cold mountainous areas, where remote sensing technology can play a positive guiding role. ETM satellite data were used in this study and processed in various remote sensing image processing methods. Based on the establishment of interpretation signs for geological bodies, strata, magmatic rocks and structures were redefined and interpreted in detail, 1/50000 scale remote sensing geological interpretation map were compiled, and two hue anomalies were found. In the same time, alteration information related with metal mineralization was extracted, providing new basic data and prospecting targets, with good application effects. |
