Application of Comprehensive Geophysical Prospecting Method in the Prediction of Mineral Resources in Qinling with High Vegetation Coverage and Deep Cut Area

The North Qinling area is an important source of gold polymetallic resources in China, especially in recent years, the periphery of the Mangling pluton is one of the important ore concentration areas of the North Qinling metallogenic belt, and its metallogenic effect and ore-controlling system have attracted much attention. However, the densely forested terrain in the area is severely cut, and no systematic geophysical work has been carried out. In this paper, through the application of comprehensive geophysical method Miaogou area on the southern margin of the n North Qinling rock pythons ridge predicting prospecting and exploration deep cut and high vegetation coverage area of the Qinling metallogenic belt in the prospecting prediction techniques combination. In the work area, geophysical surveys such as ground high-precision magnetic method, IP and controlled source audio magnetotelluric survey (CSAMT) are carried out. The comprehensive geophysical method jointly interprets the contact relationship between various layers in the region and the formation of the emplacement of the hidden rock mass. The shape of the nappe and the research on the shape of the regional ore-bearing fault zone. Conduct research on the morphology of the regional ore-bearing fault zone, predict the ore-bearing location and metallogenic potential of the region, summarize the geophysical prospecting signs based on the results of engineering disclosure, delineate favorable metallogenic areas, and provide an important basis for future exploration in this area.
