| 摘 要： | 通过对荒漠戈壁区不同矿区地表疏松层中元素的分布规律研究发现:主要成矿元素和指示元素均在近地表疏松层中富集,同时,在粒级分布上又倾向于细粒级(-160目)富集,可见,在对荒漠戈壁区进行区域地球化学调查中,采集弱胶结层(10~40 cm)细粒级样品(-160目)为最佳采样介质,这样能有效地捕捉深部含矿信息.

| Abstract: | The distribution and concentration of elements were investigated from the samples collected in vertical profiles over different deposits.The results show that elements are enriched in fine fractions of the samples.In addition,elements tend to be concentrated in cemented silt and clay materials.Sampling of the fine fractions(-160 mesh) from the cemented soil horizon is an effective method for regional exploration. |
