| 摘 要： | 针对国际上层序地层学研究进展认为，层序地层学概念及其基础理论体系需要完善。表现为:（1）地震地层学的地震层序不同于层序地层学之沉积层序；（2）基于海陆相应用差异，1992年开始层序地层学由经典三分模式向现行四分模式转变，使得层序地层学发展更趋复杂化；（3）现行四分模式对应的基准面旋回实际上是非周期性的，与岸线迹线不相符；（4）简单介绍了基于经典三分和现行四分模式所修改的L-H-T层序地层学模式。重新定义层序为“一套成因相关的以残留最大水泛面及其相对应的不整合界面为界的相对整合的地层序列”。

| Abstract: | Based on the research development in international sequence stratigraphy, this paper puts some viewpoints forward as follows: (1) sequence of seismic stratigraphy is different from the depositional sequence of sequence stratigraphy; (2) after 1992 the transformation from three divided to four divided models, the difference between marine and continental depositional sequence makes sequence stratigraphy develop complicatedly; (3) the base level curve correlative to the four divided model of current sequence stratigraphy is non periodic and is not correlative to the periodicity of shoreline trajectory; (4) this paper introduces L H T sequence stratigraphy including conceptual model, diagrammatizing rules and approach of chronsequence framework, revamped base level curve correlative to systems tracts of L H T sequence stratigraphy. This paper redefines sequence as "a relatively conformable succession of genetically related strata bounded by remnant maximum flooding surfaces (RMFS) and their correlative subaerial unconformities (CSU)". |
