摘要

摘要: 东海陆架HY126EA1孔有孔虫壳体氧同位素组成具有明显的阶段性变化.通过与深海氧同位素组成曲线对比,可将氧同位素组成变化分为5期,分别对应着冰消期、末次冰期极盛期、末次冰期间冰段、末次冰期初期和末次间冰期.碳同位素组成的变化与氧同位素组成的变化基本一致.δ¹⁸O和δ¹³C的相关性在不同气候期存在明显差异,主要受陆源水和海水交换复杂程度的控制.

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.
