| 摘 要： | 利用岩石地球化学与地质相结合的找矿方法,选择云南思姑锡矿区Sn、Cu、Pb、Zn、Ag、Mo等6个元素,对矿区矿化晕进行了异常元素的相关、偏相关、聚类与因子等分析,并以传统化探处理方法(平均值+n×标准差)确定异常下限,所圈定的异常区与已知矿体基本吻合,证实了方法的有效性,进而以此方法探索找矿,提出扩大找矿远景靶区应主要向矿区南部延伸。

| Abstract: | The Sigu tin deposit is situated in the southeast of three-river metallogenic belt in southwest China. In this paper both geological and geochemical methods are introduced. The research deals with mineralized halos of six elements including Sn, Cu, Pb, Zn, Ag and Mo. The mineralized halos are studied with analysis such as correlation, partial correlation, R-type cluster analysis, factor analysis. Traditional geochemical data processing method is adopted to set the geochemical anomalous line(mean+n×standard deviation). The analysis result has proved that the anomaly agrees with the known orebodies. Based on this method, the ore exploration targets which extends to the south of the mining area is delineated. |
