| 摘 要： | 利用层序地层学、沉积学原理和方法，对琼东南盆地古近系陵水组进行了层序划分和沉积体系时空配置关系的研究。建立了陵水组的层序地层格架，将其划分为Els3、ElS2和Elsl三个三级层序，其层序和体系域变化主要受控于凹陷内沉降中心的分布位置，沉积主要受控于盆地边缘的断坡带。每个三级层序低位体系域发育局限，海侵与高位体系域发育。沉积体系构成以扇三角洲、三角洲、滨海平原和浅海为主。探讨了沉积体系的演化，总结了其时空配置关系的特点。

| Abstract: | Based on the principles of sequence stratigraphy and sedimentology, sequence-stratigraphic framework of Lingshui formation in Qiongdongnan Basin was established, and the temporal and spatial configure relation of sedimentary systems were also studied. The Lingshui Formation was classified into three tertiary sequences. The sequences and system tracts were controlled by distribution of the subsidence centers. And the deposition was mainly controlled by the fault-break zones in the basin boundary. Each LST are limitedly developed, and the TST and lIST are well-developed. There are six delxxsitional systems in this area, they are fan delta, delta, coastal plain, and shallow sea respectively. The evolution of the depositional system was studied and the characteristics of the temporal and spatial relation was summarized. |
