The study of mixing rates and sedimentation rates in Meizhou Bay sediments

摘要

-The applicability of the doubie-layer model for 210Pb chronology in coastal marine environments was discussed,which is successfully used in the study of mixing rates and sedimentation rates in Meizhou Bay. Differences among sedimentation rates deduced from 210Pb, 210Po, and 137Cs were compared. Mixing rates in the sediment surface layer were determined by means of excess 234Th.
