In order to select suitable geophysical methods for deep exploration in the Jiaodong gold concentration area,and to determine the deep structural position,occurrence,and relationship with geological bodies of the Xilin gold metallogenic belt,this study summarized the geophysical exploration indicators and constructed a deep geological-geophysical exploration model.3 typical electromagnetic methods,including AMT,CSAMT,and WFEM,were conducted in the Xilin gold metallogenic belt.The detection results of the 3 electromagnetic methods were compared and analyzed in terms of anti-interference ability,detection depth,resolution,and accuracy through theoretical analysis,field measurements,and drilling verification.The experimental results showed that WFEM outperformed the other two methods in terms of anti-interference ability,detection depth,resolution,and accuracy.It can accurately determine the scale and depth of geological bodies along the measured lines,effectively constrain the development position and deep changes of the Xilin fault zone,as well as its relationship with the rock mass.
