Abstract:
      The Xiqinggangping gold deposit located in the middle of the Kangshan-Qiliping metallogenic belt in Xiongershan, western Henan.It is a typical tectonic altered rock type gold deposit. Comprehensive prospecting methods such as rock and soil geochemical survey, EH4 and dual-frequency IP sounding and controllable source audio magnetotelluric survey have been carried out in the mining area. The verification of engineering results show that geochemical exploration plays a very important role in narrowing the prospecting scope and delineating the prospecting target area, EH4 and dual-frequency IP sounding have a good effect on determining the location and extension of the fault zone, and the effect of detecting sulphide metal deposits is general. The controllable source audio frequency magnetotelluric survey is not effective in guiding the prospecting of ore deposits. The deposit potential is evaluated and there is still great prospecting potential in the deep part of F1, F6 and F7 vein. In addition, the geochemistry of surface and borehole shows that the mining area has the potential to form lead-zinc polymetallic deposits.
