摘要
文章总结了南客寮矿区的地质特征,开展1∶10 000土壤地球化学测量工作;研究了土壤地球化学数据的含量特征、分布型式、组合分析,并进行了单元素异常及综合异常圈定。由元素的含量特征及分布型式可知Sn、Bi、Zn、Au、Pb、As、Sb、Ag元素含量相对较高、变异系数较大,表明以上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、相关分析等多元统计分析表明,Cu、Zn、Pb、As、Sb可以作为本区找矿的指示元素;通过对单元素异常及综合异常的圈定,认为AS4、AS6、AS5等3个综合异常带具有良好的找矿前景,为矿区今后工作的重点靶区。
The geological characters of Nankeliao mine area were summarized ,and the 1∶10 000 soil geochemical survey was done .By analyzing the geochemical data with respect to their elemental con-tent ,distribution modes and combination character ,the single element anomaly and synthetical anom-aly were marked .According to the elemental content and distribution modes ,it is found that the con-tent of such elements as Sn ,Bi ,Zn ,Au ,Pb ,As ,Sb ,and Ag is relatively higher and their variation coefficient is larger than other elements in the mine area ,w hich is probably caused by secondary en-richment .The results of factor analysis ,cluster analysis ,correlation analysis and multivariate statis-tical analysis show that the elements of Cu ,Zn ,Pb ,As and Sb represent the significant minerals in this mine area ,w hich can be a good mineralization prospecting factor .According to the evaluated sin-gle element anomaly and synthetical anomaly distribution ,it is concluded that three synthetical anom-aly zones AS4 ,AS6 and AS5 are the most potential mineralization districts for future targeting work .
