摘要: 以地层过程—响应沉积动力学为理论基础,以中期基准面旋回为周期,以短期基准面旋回为成因地层单元,较为详细地讨论了层序结构、层序叠加样式与可容纳空间 /沉积物补给通量比值 (A/S比值 )变化、基准面升降幅度及沉积动力学条件的相互关系,描述了不同结构和叠加样式的短期基准面旋回在中期基准面旋回中的分布规律,最终提出以中期基准面旋回为单元的标准层序模式。有意义的是,上述理论分析结果与四川、鄂尔多斯和辽河等盆地中的中、新生代陆相地层高分辨率层序地层分析结果完全一致,说明高分辨率层序地层学理论及其技术方法非常适合于中国广泛分布的中、新生代陆相含油气盆地的层序地层学研究。Abstract: The sedimentary dynamic analysis of sequence structure and stacking pattern of base-level cycle is one of the most important contents to integrate and apply the theory and technology of high-resolution sequence stratigraphy.In this paper,the author takes the stratigraphic and sedimentary process-response dynamic principles as a theoretical basis, middle term base-level cycle as a period and short term base-level cycle as a genetic stratigraphic unit to discuss the relationship between the sequence structure,the sequence stacking pattern,the ratio variation of accommodation space to sedimentary alimentation (A/S ),the rise or fall range of base-level and the sedimentary dynamic condition.It shows that the short term base-level cycles with different sequence structure and stacking pattern distribute regularly in the middle term base-level cycle, and suggests the standard section architecture of the middle term base-level cycle.It is very significance that the sedimentary dynamic analysis on the sequence structure and stacking pattern of short or middle term base-level cycle in terms of theory mentioned above is completely consistent with the application aspects of the high-resolution sequence stratigraphy of the Mesozoicor Cenozoic terrestrial stratigraphy in Sichuan Basin,Ordos Basin and Liaohe Basin and so on and proves that the theoretical systerm and the analytical technology of the high-resolution sequence stratigraphy and completely adapted to employ the sequence research of the Mesozoic or Cenozoic terrigenous oil-bearing basins developed widely in China.
