| 摘 要： | 以江西遂川金坑土壤化学采样为研究对象,对研究区内土壤中十种金属元素Au、Ag、As、Sb、Cu、Pb、Zn、W、Bi、Sn的化探数据进行了分析,运用概率统计分析,剔除特高、特低含量值,形成数据正态分布,运用MAPGIS的空间分析能力,圈定十种金属元素的异常范围,得到土壤中十种金属元素分布状况及其特征.通过主成分分析,减少了综合异常圈定的影响因素.结果发现Au、Ag、Cu、Pb、Zn等地球化学异常密集分布,这些发现将对进一步勘查提供有力的支持.

| Abstract: | In this paper,soil sample of Jinkeng region in Suichuan was taken as research object,the geochemical data of metal elements which include Au,Ag,As,Sb,Cu,Pb,Zn,W,Bi and Sn were analyzed.The normal distribution data was formed by using probabilistic statistical analysis to exclude special high and low value.The abnormal range of 10 metal elements was delineated by using spatial analysis of MAPGIS,and the factors which influence abnormal range were reduced by using principal component analysis.Finally the dist... |
