摘要
以地壳波状运动理论为指导思想，综合分析岩芯、钻井、测井、录井等资料，应用沉积盆地波动过程分析方法，研究了塔里木盆地、渤海湾盆地、三水盆地演化过程中的主要周期。研究成果表明：２２０±Ｍａ周期是银河年周期对地球的影响，６５±Ｍａ周期反映了太阳系在银道面上、下的运动周期及地幔对流周期对地表作用结果；１０±Ｍａ周期是太阳能量的变化周期在地表沉积物中的反映。这些不同级别的周期波作用于地球表面，其叠加耦合的结果将造成不同时期地层的沉积或剥蚀速度的变化及其量级的差异，以及剥蚀事件的非等时性。地壳的波状运动说明，地壳的负向运动（沉降）与正向运动（抬升）是对立统一的，它们都应隶属构造运动的范畴，正向运动仅是构造运动的一个方面。
The cycles and their originations in the evolutionary processes of the Tarim basin, Bohai Gulf basin and Sanshui basin have been studied comprehensively by using the information from the core, drilling and well logging with analysis of wave processes, in light of wave theory of the Earth′s crust movement. It is shown that there are the cycles of 220±, 65±, 30± and 10±Ma in the evolution of basins. The cycle of 220±Ma results from the affection of galactic rotation on the Earth, the cycles of 65±Ma and 30±Ma represent the down up movement of the solar system around the Milky plane and mantle convection and the cycle of 10±Ma is the reflection of the change of solar energy in surficial deposit. These cycles of different grade interfere with each other resulting in the change of deposition and erosion rate and non isochronism of the erosional processes. The wave movement of the crust shows that the negative movement and the positive movement are unity of opposites. They all belong to the domain of tectonic movement, and the positive movement is just one side of them.
