| 摘 要： | The aim of this paper is to study the REE geochemistry of the Shenzhen Bay (SZB) and Dapeng Bay(DPB) modern sediments, discuss their REE distribution patterns, reveal the REE geochemical difference between the two bays which share the same material source but are deposited in different sedimentary environments, and expound their dynamic changes.It can be concluded that the SZB and DPB sediments are essentially of continental source.Their REE distribution patterns are quite different from those of Pacific pelagic sediments, but are very similar to those of South Chi-na granites.Because of different sedimentary environments prevailing in the SZB and DPB, some REE fractionation would have taken place in the sediments of the two bays.

| Abstract: | The aim of this paper is to study the REE geochemistry of the Shenzhen Bay (SZB) and Dapeng Bay (DPB) modern sediments, discuss
their REE distribution patterns, reveal the REE geochemical difference between the two bays which share the same material
source but are deposited in different sedimentary environments, and expound their dynamic changes. It can be concluded that
the SZB and DPB sediments are essentially of continental source. Their REE distribution patterns are quite different from
those of Pacific pelagic sediments, but are very similar to those of South China granites. Because of different sedimentary
environments prevailing in the SZB and DPB, some REE fractionation would have taken place in the sediments of the two bays. |
