Comprehensive Application of Exploration Techniques and Methods of Dajing Copper Polymetallic Deposit in Inner Mongolia and Rapid Prediction and Loca-tion of Prospecting
Dajing copper polymetallic ore in Inner Mongolia is a magmatic hydrothermal filling deposit.Ore bodies mainly occur in Linxi Formation of Upper Permian,and the main useful components of the orebodies are Cu,Sn,Ag,Pb,Zn.In order to summarize the geochemical anomaly characteristics and the resistivity characteristics of the ore body,multiple methods were used in the mining area including geochemical soil secondary halo,controlled source audio magnetotelluric survey,radon survey and gravity survey etc.Through the above methods,the favorable prospecting spaces can be discovered,and the fault structures related to mineralization also can be inferred by Measuring radon gas.Deep rock mass is detected by gravity survey to trace the hydrothermal source in the mining area.Finally,through comprehensive analysis,rapid prediction and positioning of ore prospecting will be carried out,which will lay a certain research foundation for further work.
