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。 By observing and measuring the stratigraphic section of Emei Mountain, the clay rock near the boundary is collected and the trace element geochemistry characteristics are analyzed. Through the standardization of rare earth elements and other trace elements, the trace elements Trace effect and trace element geochemical anomalies, and initially explored the source of boundary clay rocks, providing the basis for the research work of Permian-Triassic in the world.
