| 摘 要： | 我国东部大多数中新生代含煤和含油气盆地是陆相断陷盆地，其层序形成和演化主要受控于幕式构造作用。笔者通过典型断陷盆地层序层的研究，根据构造沉降及其可容空间变化特点，提出了拉张型，挤压型，走滑－伸展型和热沉降型四种层序样式，并总结了各种层序中体系域构成特点，概括了多幕裂陷型，断坳转化型和走滑－伸展型三种层序地层格架模式。

| Abstract: | Most Mesozoic-Cenozoic coal- and petroleum-bearing basins in eastern China are continental down-faulted basins, in which the formation and evolution of the sequence are mainly controlled by episodic tectonism. Based on a study of the sequence stratigraphy of some typical down-faulted basins, four sequence patterns have been identified according to the features of tectonic subsidence and its accomondation space; extensional (or tenso-shear), compressional (or compresso-shear), strike-slip-extensional and thermal subsidence patterns, each of which has its own characteristics of internal composition of system tracts. According to the characteristics of rift-filling sequence, three types of sequence stratigraphic framework have been recognized: polyphase rifting type, the type of transformation from rifting to depression, and strike slip-extensional type. |
