Application of Remote Sensing Technology in 1：50000 Mineral Investigation in Dahulishan Area

Taking the 1:50 000 minerals prospect investigation in Dahulishan area in western of Inner Mongolia as an example,we discuss the application and specific work method of remote sensing technique.The applications of remote sensing include information extraction of geological bodies,linear and circle structure,mineralization and alteration,and data extraction by the Principal Component Analysis,and remote sensing geological interpretation map by the superposition integration of standardimage with other data sources on the digital plat form of RGM AP.The results show that the full application of remote sensing technique in 1:50 000 mineral prospect investigation,combining with geology,geophysics and geochemistry,has been able to guide the work of prospecting quickly and efficiently on the ground,and has played an important role in selecting for ecasttarget area.
