Abstract: In order to solve the problem of searching for deep concealed ore bodies in Lunshan Gold District,Jiangsu Province,the characteristics and parameters of geoelectric extraction elements in the mining area are counted and discussed.The anomaly classification criteria are determined by calculating the background value of each element,and 8 element anomalies including Au,Ag,As,Sb,Hg,Cu,Pb and Zn are delineated.Cluster analysis and factor analysis show that the mineralization of Au in the mining area is closely related to polymetallic sulphide and mainly migrates and precipitates in the form of sulfur complexes,and Ag,Cu element anomalies can be used as indirect prospecting indicators.Taking the Au element anomaly extracted by geoelectric txtraction as the main basis,based on comprehensive consideration of the fittings status of Au and other element anomalies and the geological features,3 mineralization prospects were delineated,No.1 prospect has greater prospecting potential of discovering concealed ore bodies and can be taken as the important prospecting area;No.2 and No.3 prospects have certain prospecting potential.
