| 摘 要： | 本文以内蒙古东乌珠穆沁旗萨麦地区1:5万巴彦塔拉等4幅区域地质调查范围为研究区,以ETM+影像数据为信息源,以波谱理论为基础,从遥感图像中提取蚀变信息继而进行遥感找矿实践。针对区内铁染、羟基蚀变类型使用主成分分析等方法,将研究区划分为10个异常区,结合区域构造特征情况,对异常区域开展了1:1万路线调查,综合判定后,选择了4个找矿靶区进行了化探剖面探测并进行了成果分析,结果显示遥感蚀变信息与野外调查和化探异常吻合较好。

| Abstract: | This paper takes four regional geological survey mapping area (1:5 0000) of Samai Bayan Tara and so on, East Ujimqin Banner, Inner Mongolia Autonomous Region, as the study area, using ETM+ image as data source, based on the spectral theory, information extraction and remote sensing prospecting practice from remote sensing images. According to the iron stain and hydroxyl alteration types, results of the principal component analysis methods in the study area, the study area can be divided into 10 anomaly areas. Combined with the regional tectonic features, we have launched a 1:1 0000 route survey of abnormal area, after comprehensive judgment, 4 prospecting target areas of geochemical exploration and proifle are chosen. The results show that the remote sensing alteration information is matched with the ifeld investigation and geochemical anomalies. |
