多幕裂陆作用是指裂谷盆地在发育过程中构造作用的幕式性与脉冲性.其作用过程通常与盆地的构造格架变革、构造沉降幕、岩浆活动幕及沉积充填幕相匹配,它们实际上是多幕裂陷作用的构造、岩浆和沉积响应,因而具备构造信息。构造低架、构造沉降及沉积充填与裂陷幕发育过程基本同步,岩浆活动通常集中于两幕裂陷之间。所以重视上述盆地记录研究,有助于揭示裂陷盆地的发育过程。
Multi-episodic fissures are the episodic and impulsive tectonic processes during the development of the rift basins. Its process is usually matched by tectonic framework transformation, tectonic subsidence curtain, magmatic curtain and sedimentary fill curtain in the basin. They are actually tectonic, magmatic and sedimentary response of multi-curtain tectonics and thus have tectonic information. The structure of low shelf, tectonic subsidence and sedimentary filling are basically synchronous with the development of the fissure curtain. Magmatic activity usually concentrates between the two episodes of rifting. Therefore, attention to the record of the basin research, help to reveal the development of rifted basins.
