Planktonic foraminifera assemblages of 79 core top samples from the western and southern areas of the Indonesian Archipelago were grouped using cluster analysis. The results indicate that foraminifer assemblages make it possible to sub-divide the studied area in five provinces. The modern ocean characters and the surface sediment features from the five provinces are studied in the project.

本项目依据印度尼西亚多岛海及邻区七十九个海底表层样品的浮游有孔虫组合聚类分析结果，将该区划分为五个洋流活动区，对各区现代海洋学性质与海底表层沉积物特点进行对比研究。

The tuned Brunhes/Matuyama paleomagnetic polarity reversal agrees well with an age of 0.78 Ma dated previously. The tuned ages for several planktonic foraminifer Mo-events also agree well with published dates, and new ages for some other bin events in the South China Sea are also estimated.

调谐结果显示，1143站190.77m、191个冰期、间冰期的深海沉积记录了5.02Ma的南海古海洋学历史；1143站布容／松山磁性反转事件的年龄为0.78Ma，与前人研究结果一致；15个识别出的浮游有孔虫生物事件年龄部分与已经发表过的年龄相吻合，部分为该生物事件在南沙海区的新年龄。

The upper layer, with homogeneous composition, is mainly composed of intact phosphatic foraminifer fossils and nannofossils as well as abiotic carbonate fluorapatites, representing the biologic and autogenic origin. However, the lower layer, with visible metasomatic texture and relatively high Si, Al, K and Fe, is notably different from the upper one, and seems to have been formed mainly by replacement of carbonates.

上层磷酸盐由大量形态结构清楚的磷酸质有孔虫和超微化石以及非生物碳氟磷灰石组成，成分均一，杂质少，表现出生物成因和原生白沉积特点；下层磷酸盐变化复杂，具有特征的交代结构，混杂较高的Si、Al、K、Fe成分，显示以磷酸盐交代碳酸盐成因为主。

Microfossil assemblages and foraminifer isotopes from the upper part of ODP Hole 807A on the Ontong Java plateau were studied to provide evidence for discussing Late Quaternary productivity variations with glacial cycles in the western equatorial Pacific.

Carbonates also occupy an important component, with E271 from 5.9% to 27.57% and E272 from 6.67% to 38.20%. A few foraminifer fossils were found in the sediment cores. These sediments are rich in Cu, Pb and Zn which are fallout from hydrothermal plume with iron oxides.

热液桩的沉积作用，使Cu、Pb和Zn在沉积物中富集，Cu/Fe、Pb/Fe和Zn/Fe比值低于热液喷口处的颗杜物中值，Pb表现出在海水中运移距离较短或者只有少量Pb随热液柱扩散运移。
