In order to development the Aero Geophysical Survey and technology application in the key metallogenic zone ,China Aero Geophysical Survey and Remote Sensing Center for Land and Resourc conducted 1:50 000 aeromagnetic surveys in Dunhuang-Akesai from 2015~2016. They organized ground verification and collected magnetic parameters . In the process, they collected a series of Nb-Ta deposits information and date such as YuShishan ore. According to the classification of different types of deposits, the researcher compared this geological datas with aeromagnetic ΔT characteristics. The result shows these Nb-Ta deposits has typical magnetic field zonation indication on the aeromagnetic ΔT anomaly map. And this research has important guiding significance in expanding the known scale of Nb-Ta ore and in finding new rare metal deposits.
