摘要
文章总结了金钩仔矿区的地质特征,对1∶10 000土壤地球化学测量的结果进行分析,研究了地球化学元素的含量特征、分布型式,并进行了组合分析、单元素异常及综合异常的圈定。元素含量特征及分布型式表明,矿区Ag、Pb、As、Sb、Hg元素含量相对较高,变异系数比较大,这些元素易参与次生富集作用,形成地球化学异常;因子分析、聚类分析等多元统计分析表明,Cu-Pb-Zn、Ag-As-Sb-Hg 2类元素组合代表矿区主要成矿元素的次生富集组合,可作为本区较好的找矿指示元素;通过单元素异常及综合异常的圈定认为,Au-As-Cu-Zn综合异常带、Au-Ag-As综合异常带、Cu-Pb-Zn综合异常带和Au-As异常带均具有较好的找矿前景,为矿区今后工作的重点靶区。
The geological characters of the J ingouzai gold deposit in Yangxi County, Guangdong Prov- ince are summarized. The 1 ： 10 000 soil geochemical survey is done. By analyzing and synthesizing those geochemical data with their elemental contents, distribution and combination characters, circle- marked single and synthetical element anomalies, the following results are gotten： there are relatively higher Ag, Pb, As, Sb, Hg contents and coefficient variation than other elements in the Jingouzai gold deposit, which probably participates in secondary enrichment and results in geochemical abnor- malities. The results of multivariate statistical analysis such as factor analysis, cluster analysis show that Cu-Pb-Zn and Ag-As-Sb-Hg combination represents the significant mineral secondary enrichment in Jingouzai gold deposit, which can be a good symbolic factor mineralization prospecting. After the circle-marking of the single and synthetical element anomalies, it is proved that the Au-As-Cu-Zn, Au-Ag-As, Cu-Pb-Zn and Au-As anomalous zones are the most potential mineralization districts for future targeting work.
