Abstract:
Based on the quantitative analysis of foraminifera from Core NBBL and the AMS14 C dating,Holocene sedimentary environment change at Beilun,Ningbo was reconstructed. The result showed that a transgression-regression cycle occurred in this area during the middle and late Holocene.At7300 cal.aBP,the environment of Beilun was influenced by the marine setting.During 7150—2480 cal.aBP,the sediment was under a shallow marine facies.After2480 cal.aBP,the sea water became shallower,and finally retreated from this area.
