| 摘 要： | 本文从实际资料出发初步探讨了多年来一些区域化探工作者使用传统的浓度克拉克值来估计不同地质单元不同元素的富集与贫化规律的问题。提出了以元素的区域背景平均值代替地壳克拉克值计算区域浓集系数的新方法,研究微量元素的区域空间分布规律,取得了较好的效果。

| Abstract: | According to data available,the present Paper dealt prelimboily with the problemof concentration clarke values used traditionally by some regions geochemists for estimatingenrichment and impoverishment of different elements in different geological units.On such a basis,a new method for calculating regions concentration coefficients has been advanced in whichaverage regional background values of elements are used instead of their clarke values in thecrust,and the regional spatial distribution patterns of trace elements have been Studied,with fairly good results obtained. |
