| 摘 要： | 对伶仃洋沉积物表层中的有孔虫生物群与埋葬群进行了比较分析,有效地分辨出河口湾内拦门沙区的高速沉积带、深槽里的有孔虫异地埋葬分子、东、西槽内陆架咸水作用的差异以及沉积物不同搬运方向等.证明用有孔虫生物群与埋葬群的对比分析可判释出沉积动力环境的更细微的差别和变化,较单纯据死有孔虫群的分析效果要好.

| Abstract: | Difference in environmental explanation from analysis of living and dead foraminifera in the Lingdingyang estuary of the Zhujiang River shows the frequent depositional belt in the river-mouth-barregion, the exotic burial foraminifera assemblages in deep-water channels, the difference in the intrusive process of the shelf-salt-water and in the transportation direction of sediment between the east channel and the west channel, etc.It is possibly provided that the living and dead foraminifer a may be the trace for explaining the smaller difference and change of the environment, and this method will be better than that only using the dead foraminifera assemblages. |
