Abstract: In the Qimantage region of East Kunlun Mountains,Xinjiang,the natural environment is bad and the level of exploration is lower; and so the 1 :50 000 aeromagnetic survey is a fast and efficacious geophy sical method,which can ascertain the magnetic anomaly's characteristic and the magnetism's distributed regulation in faster and accurate way,specially in vastarea.Through ground magnetic survey for the special significant aeromagnetic anomaly,the geological cause of magnetic anomaly can be proved up quickly; the oreguide can be discovered opportunely; the target of prospecting can be focused on efficaciously; and that the process of the mineral exploration and development in the Qimantage region of East Kunlun Mountains would be accelerated.
