According to general rule, volcano eruption function from strong to weak, finally arrives the deposition, composes a volcanic eruption - depositionalcycle.
根据一般规律，火山的喷发作用从强到弱，最后到沉积，组成一个火山喷发—沉积旋回。

Changes in depositional base-level cycle control the development and evolution of sequence stratigraphy.
沉积基准面旋回变化控制着陆相层序地层的形成与演化。

Moreover, the persistent depositional time and depositional rate of the high-frequency sequences are estimated based upon the information of the Milankovitch Cycle captured in the analysis.
