摘要:
为解决江苏仑山?鹂笄罢疑畈恳筇宓奈侍猓钥笄氐缁崛≡靥卣鞑问型臣撇⑻致郏ü扑愀髟氐谋尘爸等范ㄒ斐；直曜迹ΧAu、Ag、As、Sb、Hg、Cu、Pb、Zn等8种元素异常。聚类分析和因子分析表明，矿区内Au成矿与多金属硫化物关系密切，多以硫络合物形式迁移、沉淀，Ag、Cu元素异常可作为间接找矿标志。以地电化学提取Au元素异常为主要依据，综合考虑Au与其他元素异常套合情况，并结合地质特征，圈定了3处成矿远景区，1号成矿远景区找矿潜力较大，具有发现隐伏矿体的可能，可作为重点找矿区域；2号、3号成矿远景区具有一定的找矿潜力。

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.
