粤北山池村矿区物化探异常特征

采用聚类分析与因子分析方法,确定了山池村矿区的主要成矿元素是Pb、Zn,成矿元素组合为Pb、Zn、Cu、Bi、Mo;以1∶10 000物化探异常工作成果为基础,对山池村矿区的物化探异常进行了初步分析。结果表明,土壤地球化学测量特征表现为Ag、Pb、Zn组合异常,结合区内1∶50 000高精度磁法测量表明含矿岩体具有低阻、高极化率特征。根据成矿地质条件与物化探异常组合,确定AP1号异常区为本区重点找矿靶区;在靶区内布置3条激电测深剖面展开异常查证工作,在有利成矿部位实施1个钻孔,见到了6条铅锌矿体。根据矿区成矿地质条件和物化探异常特征,结合钻探工程的验证结果,指出AP1号异常区为下一步重点工作区。

Characteristics of geophysical and geochemical anomalies of the Shanchicun ore district, NorthernSGuangdong

To the geophysical and geochemical anomalies of the Shanchicun ore district, conducted a preliminary analysis, which based on the work results of 1:10,000 geophysical and geochemical anomalies, using the combination of factor analysis and cluster analysis, identified the main ore-forming elements of the mine is Pb, Zn,and metallogenic element association is Pb, Zn, Cu, Bi, Mo. According to the analysis of theresults of high-precision magnetic survey shows,the host rock has low resistance, high polarization characteristics. By the analysis of mineralization geological conditions and geophysical and geochemical anomalies anomaly, believed No.AP1 anomaly is the focus of prospecting area. To start the anomaly inspection work, wearranged three IP sounding sectional and andrilling in the favorable metallogenic part of the No.AP1 anomaly, found six lead-zinc ore bodies. According to metallogenic geological conditions and geophysical and geochemical anomalies, and combined with verification drilling project, pointed out that AP1 anomaly region is the next verification project area.
