| 摘 要： | 对东海84个表层沉积样品和5个重力柱状样中的翼足类和浮游有孔虫丰度、浮游有孔虫碎壳率和底栖有孔虫群中胶结质类的比例等进行了定量分析,确定了东海现代文石补偿深度（ACD）位于约600 m处,碳酸盐溶跃面在约1 400 m处.末次冰期时随着碳酸盐溶解作用的显著减弱,ACD大幅度下降至现代的1 000 m之下. |
| 关 键 词： | 翼足类 文石补偿深度 碳酸盐溶解作用 末次冰期 东海 |

| Abstract: | A total of 84 surface sediment samples and five gravity cores from the East China Sea have been analyzed quantitatively for the abundance of pteropods and planktonic foraminifera,planktonic foraminiferal fragmentation,and the ratio of agglutinants in benthic foraminiferal fauna.The results indicate that the modern pteropod or aragonite compensation depth(ACD) is at about 600 m in the East China Sea and the carbonate lysocline at approximately 1 400 m.The ACD,however,was at least 1 000 m deeper than today during the last glacial due to a great decrease in the carbonate dissolution. |
| Keywords: | pteropods aragonite compensation depth carbonate dissolution last glacial East China Sea |
