摘要
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。
A preliminary analysis was conducted about the geophysical and geochemical anomalies of the Shanehicun ore district, which based on the work results of 1：10 000 geophysical and geochemical anomalies, by using the combination of factor analysis and cluster analysis. It is identified that the main ore-forming elements of the mine are Pb, Zn and metallogenic elements combination are Pb, Zn, Cu, Bi, Mo. The results show that the characteristics of soil geochemical survey are Ag, Pb and Zn assemblage anomalies. The analysis of the results of high-precision magnetic survey shows the host rock have low resistance and high polarization characteristics. On the basis of the analysis of mineralization geological conditions and geophysical and geochemical anomalies anomaly, it is determined that the abnormal area of AP1 is the key prospecting target area in this district. To start the anomaly inspection work, 3 polarization sounding sections are arranged in the target area and then one tilling is implemented in favorable position of mineralization and 6 lead-zinc ore bodies have been found. According to metallogenic geological conditions and geophysical and geochemical anomalies, and combined with verification drilling project, it is pointed out that AP1 anomaly region is the next verification project area.
