摘要

Abstract

Analysis of232Th

230Th

and228Th in sediments showed that there was an excess of228Th over that supported by the parents232Th or228Ra in sediments in many regions. This excess228Th with a half-life of 1.91 years can be used for dating purpose over a time period of the order of a decade

so average sedimentary rates in the Yalujiang River Estuary

and in the Huanghe River Estuary and its adjacent Laizhou Bay can be obtained from decreases in the excess228Th activity as a function of depth in sediment.
