【摘要】 通过对峨眉山地区地层剖面的实地观察和测量,采集界线附近的粘土岩,分析了该区微量元素地球化学的组成特征,并通过对稀土元素标准化图解和其它微量元素的研究,利用微量元素的示踪作用以及微量元素地球化学异常,初步探讨了界线粘土岩的来源,为全球二叠—三叠界线研究工作提供依据。更多还原

【Abstract】 Based on the Emei Mountain area stratigraphic section of field observations and measurements,collected near the boundary of the clay rocks,geochemical analysis of the area of the composition of trace elements and rare earth elements through the standardization of graphic and other trace elements in research,use of trace elements Tracing the role of trace elements and geochemical anomalies,discussed the boundaries of the clay-source for global Permian-Triassic boundary provide the basis for research work.更多还原
