| 摘 要： | That the contents and compositions of trace elements, especially REE in sedimentary rock and agustite originating from inarticulate brachiopods, conodont, etc. change in the vertical direction usually has a close relation with the stratigraphic boundary of important biologies. This paper systematically analyses REE and 16 trace elements such as U, Th, Sr, Ba, Co, Ni, Cr, V, Cu, Pb, Zn, Sc, Au, As in sedimentary rocks and the agustite on the standard stratified section of the Cambrian-Ordovician Boundary in Dayangcha, Huniiang, Jilin Province. Based on this, the authors investigate the REE distribution pattern and the law of the contents and compositions of trace elements changing, providing the geochemical evidence for building stratified sections of the Cambrian-Ordovician boundary and discussing sedimentary environments.
