| 摘 要： | 本文通过对冲绳海槽Ｄ－０８６孔颗石藻化石的研究，自下而上划分出三个颗石藻化石组合：Ｇｅｐｈｙｒｏｃａｐｓａａｐｅｒｔａ－Ｇ．ｏｃｅａｎｉｃａ组合，Ｇｅｐｈｙｒｏ－ｃａｐｓａｅｒｉｃｓｏｎｉｉ－Ｃｏｃｃｏｌｉｔｈｕｓｃｒａｓｓｉｐｏｎｓ组合，Ｅｍｉｌｉａｎｉａｈｕｘｌｅｙｉ－Ｇｅｐｈｙｒｏｃａｐｓａｏ－ｃｅａｎｉｃａ组合；划分出Ｅ．ｈｕｘｌｅｙｉ带和Ｅ．ｈｕｘｌｅｙｉ高峰带的界线；每一个颗石藻化石组合代表一个气候期，它们分别与标准气候期的玉木亚间冰期，晚玉木冰期和冰后期相当。

| Abstract: | Calcareous nannofossils for the primary study are taken from D-086 core in the Oki-nawa Trough.There are three assemblages recognized,from bottom to top of the core,i.e.,Cephyrocapsa aperta-G.oceanica;Gephyrocapsa ericsonii-Cocclithus crassipons and E-miliania huxleyi-Gephyrocapsa oceanica. The age of stratigraphy,and the boundary be-tweed E.huxleyi zone and the peak zone of E.huxleyi,were discussed.Each of the threeassemblages represents a climatic period,corresponding to Wurm subinterglacial,the latelast glacial and post glacial(Holocene)respectively. |
