本文运用EBM盆地模拟系统,对中建南盆地的沉降过程进行了定量和动态模拟,得出盆地不同部位的沉降速率及变化图,再现了中建南盆地形成过程中经历的幕式沉降运动。并结合区域构造演化和盆地沉积、构造特征,分析了盆地的构造演化过程,论述了盆地的充填序列,认为盆地的幕式沉降与盆地的构造演化具有成因关系,而盆地构造沉降控制了盆地的充填过程。
In this paper, we use the EBM basin simulation system to quantitatively and dynamically simulate the sedimentation process in the Zhongjiannan Basin. The sedimentation rate and its variation in different parts of the basin are obtained. The curtain subsidence movement in the process of the formation of the Zhongjiannan Basin is reproduced. Combined with regional tectonic evolution and sedimentary and tectonic features of the basin, the tectonic evolution of the basin is analyzed, and the filling sequence of the basin is discussed. It is concluded that the curtain subsidence of the basin has a genetic relationship with the tectonic evolution of the basin, while the tectonic subsidence of the basin controls the basin Filling process.
