翘板活动是地壳波状运动中的一种型式,主要有两种活动方式。一种是发生在台地或盆地之某一隆起为枢纽的翘板活动;另一种是以断裂为枢纽的翘板回转。这种翘板回转,多在盆地沉积建造的晚期强烈活动,并促进盆地沉积中心的迁移。显然翘板活动对沉积建造和含油气盆地的成生发展都具有重要意义。本文从“地壳波浪运动与镶嵌构造”观点出发,对我国大陆及海域上几个主要含油气盆地的翘板活动的特征与油气成生关系作了初步探讨。
Rocker activity is a type of crustal wavy movement, there are two main activities. One is in the platform or basin uplift as a hub of the rocker activities; the other is the fracture as the pivot rocker rotation. This rocker gyration is more advanced and sedimentary-intensive activity in the basin and facilitates the migration of sedimentary centers in the basin. Obviously rocker activity is of great significance to the sedimentary construction and the development of petroliferous basins. In this paper, from the perspective of “crustal wave motion and mosaic structure”, the relationship between rocker activity and hydrocarbon generation in several major oil and gas basins in mainland China and the sea area is discussed.
