本文依据裂陷槽构造控制及演化规律的原则提出了裂陷槽构造旋回层序的概念，并同时给出了相应的三级划分方案。应用裂陷槽构造旋回层序的概念研讨了燕山地区中、新元古代裂陷槽构造旋回层序的发育特征。燕山裂陷槽发育４个构造阶段旋回层序，即裂张断陷、裂张均衡、均衡负载和盖层构造阶段旋回层序，其中又有序叠加了１８个构造期和８２个构造幕旋回层序。前一类层序主要受控于导致裂陷槽形成、发育的区域构造；后两类构造旋回层序受裂陷槽构造演化及所驱动的构造海平面双重控制
Based on the principle of tectonic control and evolution of rift trough, the paper proposes the concept of the cycle sequence of rift trough structure, and at the same time gives the corresponding three-level scheme. Applying the concept of tectonic gyration sequence in the rift trough, the developmental characteristics of the structural sequence of the Meso-Neoproterozoic rift trough in Yanshan area are discussed. Yanshan rift trough developed four structural stages of the gyration sequence, that is, fractured Zhang fault, fracture equilibrium, equilibrium load and the caprock structure of the cycle sequence, which in turn superimposed 18 structural tectonics and 82 tectonic episodes Sequence. The former type of sequence is mainly controlled by the regional tectonics that led to the formation and development of the rift troughs. The latter two types of tectonic gyration sequences are controlled by the tectonic evolution of the rift troughs and the dual control of the tectonic-sea level driven
