Highlights

In order to solve the problem of prospecting around and deep prospecting in Daiyinzhang mining area in Wutai County,Shanxi Province,the geoelectrochemical exploration method was carried out in the sections of three profiles 6,8 and 12 lines in the mining area,and the geoelectrochemical exploration method test under the conditions of energization (dipolar geoelectric extraction) and non-energization (foam-plastic adsorption extraction) was compared and analyzed in order to verify the feasibility of the method in the area and the influence of the applied electric field on the exploration effect.The results show that the geoele-ctrochemical extraction anomaly is clearly displayed above the known gold orebody,which corresponds well to the occurrence location of the gold orebody,and the exploration effect is remarkable,and it is effective and feasible to use geoelectrochemical methods to find hidden gold deposits in Wutai area of Shanxi Province.The applied electric field does improve the efficiency of geoelectrochemical extraction,the detection depth is also greater than the adsorption extraction without electricity,which is more sensitive,and it can clearly show the hidden orebody and weak mineralization abnormality.The anomaly corresponds to the burial location of the deep orebody,and the extracted orebody information is more comprehensive and complete,which has a good effect on further analysis of the location and distribution form of the underground orebody,and it can play a good indicator effect in deep prospecting prediction.
