The Dimunalike iron ore belt is an important iron ore exploration area in western China, where the Dimunalike iron ore deposit, the Yuling iron ore deposit and the Hesu iron ore deposit were discovered. Its geological conditions are superior and the potential for prospecting is huge. Nevertheless, due to its special geological structure and harsh natural geographical conditions, there is a great difficulty in the mineral exploration. In this study, the authors made full use of WorldView-2 high spatial resolution remote sensing data and aeromagnetic data and conducted the decomposition of the Changshagou structure-ophiolite belt to analyze remote sensing and aeromagnetic characteristics of typical deposit of the Dimunalike iron deposit. The authors established a comprehensive prospecting model of sedimentary metamorphic iron ore deposit integrated with geology, aeromagnetic and remote sensing. By using this model, the magnetite ore-bearing target can be located precisely. The results show that the combination of remote sensing and aeromagnetic methods can accurately locate the information such as ore-bearing lithology, ore-controlling structure and mineralized zone. This will improve the accuracy and efficiency of geological exploration.
