Abstract:Geochemical elements, significant indicator of environmental change,have been widely used in paleoenvironment research. By comparative analysizing of sediment’s geochemical characterstics of core PJ and core ZX-1, almost opposite relations was found between them. In Holocene, there are repeated transgression-regression cycles and the deposition profile of core PJ was in the critical zone of transgression-regression. When climate was warm and humid, sea-level rose, the sedimentary environmental salinity increas… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
