| 摘 要： | 在西藏浪卡子县穷子地区进行的1∶10 000土壤地球化学测量工作中,采用变化系数对测区10种微量元素进行地球化学统计分析,得知Au元素具有较大的成矿潜力;运用统计学软件SPSS19对10种元素含量值进行相关性分析、R型聚类分析和R型因子分析,划分出As-Au-Sb、Pb-Mo-Zn、Bi-Ag和Cu-W等4组元素组合;采用异常下限值圈定单元素异常和组合异常,结果显示As-Au-Sb组合异常和W元素异常强度较高,三级浓度分带清晰,浓集中心连续,具有较好的找矿前景;高品位Au矿化蚀变带的圈定,为下一步找矿工作提供了理论依据,显示出较好的找矿潜力。

| Abstract: | On the basis of geochemical survey at scale 1:10000 in the Qiongzi area geochemical statistic analysis on 10 microelements is carried out with variation coefficients. It was concluded that the Au has great ore-forming potential. Furthermore statistical software Spss19 is used to make correlation, R-type cluster and R-factor analysis of the ten elements and are classified the main mineralization element combinations of As-Au-Sb, Pb-Mo-Zn, Bi-Ag and Cu-W and anomlies of As-Au-Sb combination and W are circled by the lower limit value with higher strength, clear three order zonation and continuous concentration centers thus the anomlies potential. At the same time Au mineralization and alteration zones are delineated laying foundation for further prospecting in the area. |
