研究原生地球化学异常中元素的分带性具有很大的实践意义，特别是原生异常的垂直分带特征，可作为评价矿体剥蚀深度的一种指标，在国内外早已被研究和应用。 It is of great practical significance to study the zonation of elements in primary geochemical anomalies, especially the vertical zonation features of primary anomalies, which can be used as an indicator to evaluate the denudation depth of ore bodies and has been studied and applied both at home and abroad.
