摘要: 新疆东昆仑祁漫塔格一带成矿地质条件优越,是西北地区重要的找矿区域之一。2008年国土资源航遥中心开展的1:5万航磁勘查工作反映该区总体磁场较弱,单个磁异常强度较低,但反映的磁异常信息较为丰富。通过开展1:5万航磁异常查证工作,认为航磁异常较全面、客观的反映了该区的地质、构造及矿化特征,查证磁异常均与一定地质体或矿化对应。该区以铅锌矿化为主,多金属矿化常见,矿化类型以矽卡岩型为主,航磁异常主要表现在局部磁异常升高、正负磁异常过渡带部位,低缓磁异常转折部位等。矿致异常形态多样,较难识别,应以通过航磁异常间接找矿为主,指导下一步地质找矿工作,有效加快新疆东昆仑祁漫塔格一带矿产勘查开发进程。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.
