| 摘 要： | 介绍了沉积盆地波动过程分析的基本概念、发展过程、方法原理、研究步骤与应用范围,并应用此研究方法对四川盆地东北部波动过程进行了分析。通过划分波动单元、建立地层格架、恢复原始沉积厚度、计算沉积速率等步骤,建立反映盆地沉积—剥蚀过程的波动方程。应用此方程分析盆地的主要演化周期,总结沉积中心迁移规律,识别不整合面并计算剥蚀量,划分成藏旋回,识别波动转换带。此方法在中国南方海相沉积盆地可有较好的应用前景。

| Abstract: | The main concept, development, theory, working methods and applications of wave process in sedimentary basins are concerned. Based on the wave theory, the wave processes in northeastern Sichuan basin are analyzed. Through partitioning of wave unites, establishing of stratum frame, resuming of original sedimentary thickness and calculating of sedimentary velocity, the wave process equations that can indicate sediment-erosion process are set up. Applying the equations, we can also analyze the main cyclic evolution, summarize the transferred rule of a depocenter, recognize planes of unconformity, calculate amount of erosion, subdivide accumulation cyclothems, and define wave transform zone. This method will have a good applied foreground in marine strata in southern China. |
