摘　　要：关键矿产作为现代社会科技、军工、新材料的急需矿产之一,被国际社会所重视。近期在纳雍峨眉山玄武岩风化壳中发现关键金属元素异常富集。本研究以纳雍县两个典型的二叠系峨眉山玄武岩风化壳剖面为研究对象,通过对玄武岩和其风化壳中的地层结构、岩性、关键金属元素丰度分别分析,结合其所含矿物和其所处区域地质背景进行讨论,探讨玄武岩风化壳中关键金属元素的富集特征及影响因素,旨在理清风化壳中的部分关键金属元素在玄武岩风化过程中的迁移富集规律,为玄武岩风化壳中找矿提供理论支撑。Key minerals are valued by the international community as one of the much-needed minerals for science and technology, military industry and new materials in modern society. Recently, anomalous enrichment of key metallic elements has been found in the weathered crust of Emeishan basalt in Nayong. In this study, two typical Permian Emeishan basalt weathering crust sections in Nayong County are taken as the research object, and the stratigraphic structure, lithology and abundance of key metal elements in basalt and its weathering crust are analysed respectively, and the enrichment characteristics and influencing factors of key metal elements in basalt weathering crust are discussed in combination with the minerals contained therein and the geological background of the region in which they are situated, aiming at clarifying the part of the key metal elements in the weathering crust. The aim of this study is to clarify the migration and enrichment pattern of some key metal elements in the weathered crust of basalt, and to provide theoretical support for the search of minerals in the weathered crust of basalt.
