摘要: 以西昆仑大红柳滩地区花岗伟晶岩型稀有金属矿化带为研究对象,以WorldView-2高空间分辨率数据为主要信息源,在影像图制作的基础上,有针对性地进行图像增强处理,突出控矿要素和矿化信息,开展该矿种的遥感综合解译;利用ASTER数据开展与花岗伟晶岩型稀有金属成(控)矿作用相关的异常信息提取;配合适量的野外查证,分析其高分辨率遥感特征及成矿地质条件,建立遥感地质找矿模型.结果表明,利用高分辨率遥感卫星数据为主的数据源能够快速圈定找矿有利地段,满足西昆仑大红柳滩地区稀有金属矿勘查和资源评价需求,可为在相同或类似地区开展此类工作提供借鉴.Abstract: With rare metals of granite pegmatite type in the Dahongliutan area of West Kunlun Mountains as the study object and WorldView-2 remote sensing images as the major data source, the authors drew standard image map, adopted methods of image enhancement for protruding the information of ore - controlling factors and mineralization,and finally carried out an interpretation of remote sensing for mineral resources. On the basis of alteration anomaly information extraction for rare metals of granite pegmatite type by using ASTER data and a right amount of field verification, its high - resolution remote sensing characteristics and metallogenic geological conditions were analyzed,and a remote sensing geological prospecting model was established. Tt can provide the basis for finding similar minerals in the West Kunlun metallogenic belt in future. The results show that the remote sensing technology using high resolution satellite images can be used as an effective method for detection of potential mineral resources enrichment region,which can meet the requirements of rare metal mineralization belt resources exploration and assessment in the Dahongliutan area of West Kunlun Mountains and hence deserves further promotion and application in the same area or similar areas.
