Abstract

Abstract

Based on the analysis of oxygen and cqrbon data,it is found that there are clear stage changes at oxygen and carbon isotopic composition of foraminiferal crusts in HY126EA1 hole.Compared with oxygen isotopic composition of deep sea,the change of oxygen isotopic composition can be divided into five periods,which correspond to the deglaciation,the last glacial maximum,the interglacial stage of last glacial age,late last glacial age,and the last interglacial period,respectively.the change of carbon isotopic composition is almost the same as that of oxygen's.According to the correlation analysis of δ¹⁸O and δ¹³C,obvious difference in different oxygen isotopic periods can be seen,which indicates the diference of exchange of water body at different periods.
