Abstract

Based on210Pb technique, sedimentation rates of 11 cores collected from the Huanghe River estuary were determined. CaCO3 distribution of 4 cores chosen from among these was measured. Profiles of210Pb in the cores showed that the distribution of210Pb activity decayed with depth, appeared in stages and in more than one segment. The sedimentation rates,210Pb and CaCO3 data have similar distribution trend in the 4 cores. The profiles of210Pb and CaCO3 were used to study sedimentation intensity, transportation trend of material and sedimentation features in the corring area.
