摘　　要：Recent researches have demonstrated that Nd isotope is a new tool for studies on paleoceanography, ocean-crust evolution and paleoecology. Fossil phosphates and carbonates are the appropriate samples for investigating the Nd isotopic signatures of paleoseawater.We report and discuss, in this article, Nd isotopic data of determined fossils in the Cambrian-Ordovician Boundary strata of Dayangcha section, China.
