PALYNOLOGICAL ASSEMBLAGES FROM THE QUATERNARY SEDIMENTS OF THE CHANGJIANG RIVER DELTA AND THE AGE OF STRATA AND PALEOGEOGRAPHY

Through the palynological research of Quaternary sediments in Changjiang River Delta,14 spores and-pollen zones might be distinguished,reflecting the vegetation succession and climate fluctuation of Quaternary,which conforms to the climate of the world.
Zones 1-9 are thought of as Pleistocene and Zones 10-14 as Holocene based on the climatic fluctuation reflected by these zones and the comparison with the climatic stage at home and abroad.
The marine facies sediments of Quaternary in the Changjiang River Delta contain abundant fossil spores and pollen and have obvious characters.Because the warm and humid climate reflected by the palynological assemblages of marine facies sediments often fittes with the transgression,the curve line of the climate fluctuation of Quaternary in the Delta coincides with that of sea level changes.
