Abstract

Abstract

The diatom assemblages discerned in Core ZK5 can be grouped under 4 units,and can be subdivided into 24 zones.The 4 units were deposited in the Late Wiirm Glacial,Early Holocene,Middle Holocene and Late Holocene,respectively.Comprehensive analysis of microbial assemblages,lithological characteristics and age determinations of ZK5 and some other boreholes,shows that during the Late Wurm Glacial the sea level of the study area rose and fell frequently,but had principally been in the environments of estuary-bay.mainly resulted from tectonic subduction.Additionally,in this period,3 low sea levels occurred,resulting in the sedimentary environment of river.As for Holocene,sea water intruded massively and the sea level over the transgression maximum had been 5-10 m higher than that of present.
