上扬子克拉通南缘中泥盆统—石炭系地层高频层序可以划分为三个级别 ,并与层序地层学术语可以对比 :六级层序—韵律层 ;五级层序—准层序 ;四级层序—准层序组。不同级别高频层序的形成受米兰柯维奇驱动力引起的具不同周期和频率的复合海平面变化控制。克拉通边缘沉积环境中 ,低频海平面变化的上升阶段形成以淹没节拍为主的高频层序 ,而在停滞至下降阶段形成以暴露节拍为主的高频层序。所以 ,通过对不同特征的高频层序及垂向叠加的分析 ,可以求解低频海平面的变化 The high-frequency sequence of the Middle Devonian-Carboniferous strata in the southern margin of the Upper Craton can be divided into three levels and can be contrasted with the terminology of sequence stratigraphy: six-level sequence-prosodic level, five-level sequence-quasi- Order; fourth-order - quasi-sequence group. The formation of different levels of high-frequency sequence is controlled by the composite sea level change with different periods and frequencies caused by Milanovic driving force. In the depositional environment of the craton, the high-frequency sequence dominated by submerged beats at the rising stage of low-frequency sea-level changes and the high-frequency sequence dominated by exposed beats at the stagnant-descending stage. So, by analyzing the high-frequency sequence and vertical stacking of different features, we can solve the change of low frequency sea level
