中文摘要：

不同成因类型的盆地层序地层发育特征不同，而同一成因类型的盆地，不同构造演化阶段或不同的构造部位，构造／断裂活动时空演化的不均衡性导致层序地层发育的差异性。构造对盆地的层序界面形成与层序内部充填起到至关重要的作用。南海盆地珠-坳陷第三系具有下断上坳、先陆后海的双层结构，断陷期盆地由西江、恩平、惠州、陆丰、韩江凹陷组成。由于区域构造位置、各凹陷边界断裂几何形态和性质以及古地貌的不同，导致各凹陷层序地层构型与沉积充填特征的差异性。构造活动对层序地层的控制作用主要表现为：盆缘同生断裂对层序地层构型的控制作用—盆缘断裂控“型”、构造调节带对主体物源方向的控制作用—转换带控“源”、古地貌形态对砂体分布的控制作用—古地貌控“砂”。

英文摘要：

Sequence stratigraphy in basins with different genetic types has different development characteristics. In basins with same genetic type, the time-space evolution malconformation of the structural/faulting activity causes diversity of sequence stratigraphic evolution in different tectonic evolution stages or different tectonic locations. Structure plays an important role in the formation of basin sequence boundary and intra-sequence filling. Tertiary sedimentary structure in Zhu I Depression in South China Sea Basin has a two-layer structure, with a rift in the lower part and a depression in the upper part, and continental sedimentation earlier and marine sedimentation later. In rifting stage, the basin consists of Xijiang, Enping, Huizhou, Lufeng, and Hanjiang sags. Differences of regional structural location, geometry and property of sags boundary faults, and palaeogeomorphology cause variation of sequence stratigraphy configuration and sedimentary filling characteristics of the sags. Controlling effect of structural movement on sequence stratigraphy mainly appears as： effect of basin-margin syngenetic faulting on the sequence stratigraphy configuration-basin-margin faulting controlling “configuration”, control of structural accommodation zone on main provenance direction-transfer zone controlling “provenance”, and control of palaeostructure-palaeo-geomorphology morphology on sand body distribution-palaeogeomorphology controlling “sandbody”.
