| 摘 要： | 为了更好地揭示南海北部陆坡琼东南盆地晚中新世以来的沉积物输送样式,本次研究将盆地裂后期加速沉降阶段以来的沉积物充填样式作为研究对象,基于前人对这一区域潜在物源区的分析,通过对已有勘探成果的总结和归纳,对深水沉积体的类型进行识别,建立具有成因关系或相同来源的深水沉积体组合,尝试对沉积物输送样式进行划分和归类。研究结果认为,晚中新世以来,琼东南盆地主要存在海南岛物源、莺西物源、南部隆起带物源和神狐隆起物源等4个潜在物源区,沉积物输送样式可划分为垂向沉积物输送、轴向沉积物输送和转向沉积物输送3种类型。

| Abstract: | The sediment transport patterns were revealed in the Qiongdongnan Basin on the Northern Slope of South China Sea since Late Miocene by the research of the sediment filling patterns since the period of post-rift accelerated subsidence. On the basis of the previous analysis on the potential provenance, combined with the summary and induction of the exploration achievement in the research area, the types of the deep-water sedimentation were identified and the combinations of the deep-water depositional packages which have genetic relationship or the same source were built. In addition, the sediment transport patterns were classified tentatively. The results show that since Late Miocene, there are 4 potential sedimentary sources in the Qiongdongnan Basin: they are Hainan Island' sources, West Yinggehai' sources, Southern uplift' sources and Shenhu uplift' sources, respectively. The sedimentary transport patterns can be divided into three types: they are vertical direction, axial direction and turning direction sedimentary transportation. |
