摘要: 本文根据对冲绳海槽96、155号岩心中的放射虫化石分析,结合有孔虫、孢粉、植物硅酸体等综合研究资料及AMS14C测年、磁性地层学的测试结果,粗略地探讨了冲绳海槽晚第四纪以来的古海洋学特点及东海大陆架古气候变化的规律.Abstract: Based on the analysis of Radiolaria fossils,in association with the comprehensive data of Foraminifera,sporopollen, plant opal, etc.and the measuring results of AMS 14C and magnetostratigraphy, the paleooceanographic character and change regularity of paleoclimate at the Okinawa Trough in the East China Sea since Quaternary period were roughly studied.
