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.
