Ore Prospecting of Geophysics and Geochemistry in the No.IPolymetallic Deposit Survey Area of Baiyin, Gansu Province

Based on geological conditions of No.ⅠCu-Pb-Zn-Ag deposit survey area in Baiyin,Gansu Province,we used the geo-electrochemical extraction method,the soil absorption Hg measurement,the ion conductivity of soil measurement,the transient electromagnetic method and other methods to search deep hidden deposits.According to comprehensive analysis of the geophysical and geochemical anomalies,combined with the geological characteristics of the study area,the paper shows that the potential of mineral deposits is assured in this area,we found four deep ore-prospecting target,recommend three prospecting target site(i.e.,2-Ⅲ、10-Ⅰand 10-Ⅱ) which range from 300~600 m should be verified firstly,according to the findings,we know that the application of such geophysical and geochemical methods to search for concealed ore bodies in this area are available,and they should be used widely.
