Modeling of the Gist with Geophysical and Geochemical Information in the Periphery of Baiyin Ore Field and Promoted Application

To solve the problem of how to search deeply hidden deposits in the periphery of Baiyin ore field and explore the combination of effective methods which are useful to search for concealed metallic deposits,the geo-electrochemical extraction method,high resolution magnetic method,transient electromagnetic method were used to search for deeply hidden deposits in No.Ⅰ Cu,Pb,Zn,Ag deposit survey area in Baiyin,Gansu province.The geophysical and geochemical research results show that there are eighteen element geochemical anomalies and fifteen ransient electromagnetic anomalies in this area.Also,there may be volcanic apparatus here.Finally,four deep ore-prospecting target have been found,while it is noted that the further study should be carried out in 2-Ⅲ、10-Ⅰand 10-Ⅱ target sites.Moreover,according to the results of previous studies and the information obtained through the geophysical and geochemical method,the geophysical and geochemical prospecting model is applicable to the periphery of Baiyin Ore field.
