Geo-Electrochemical Method for Polymetal Ore DepositProspecting in Arid Desert Area——taking Yindonggou exploration of Baiyin as an example

To order to search deep hidden deposits in the arid desert area and the feasibility of geoelectrochemical method to find buried metallic deposits,the geo-electrochemical extraction methods are used.Using 9×10-6,18×10-6 and 36×10-6 as the three content belts,twenty-two Cu exceptional areas are found.Using 7.25×10-6,14.5×10-6 and 29×10-6 as the three content belts,thirty-two Zn exceptional areas are found.Using 100,200 and 400 μS/cm as the three content belts,eleven soil ionic conductivity exceptional areas are found.According to the scale,size,strength,change,match degree and the geological location of the anomalies,five targeted regions are found in this area,and divided into two types:two first-class targeted regions and three second-class targeted regions.
