Abstract:
Based on the multi-source prospecting information of geology, geophysics, and geochemistry on Jiuzhanggou gold deposit of structural altered rock type in Songxian County, Henan Province, this study comprehensively summarizes the integrated prospecting process and exploration model as follows:Screening the prospecting prospective areas by regional gravity and magnetic survey anomaly; Selecting the prospecting targets through the anomaly of 1:50 000 stream sediment survey; Finding the fault belts related to gold mineralization with the 1:10 000 specific geological mapping, further determining the prospecting target areas; Determining the ore-bearing potential of faults based on the anomaly of 1:10 000 soil geochemical survey to narrow down the target areas; Locating the F1 structural mineralized zone according to trace element peak position in primary halo profile; Applying high-power induced polarization (IP) sounding and EH-4 dual-source magnetotelluric(MT) sounding to identify deep structural alteration zone and orebody extension characteristics, with both methods complementing and verifying each other for positioning and prediction of deep prospecting targets.
