【Abstract】 Based on ²¹⁰Pb dating and sedimentary structure analyses for the five cores collected from the zone of the turbidity maximum in the Jiaojiang Estuary, both evolution of sedimentologic environment and sedimentary rates in the present century are studied. The shifts of the accumulating centre and their causative factors in different stages are also discussed.更多还原
