【摘要】 正演运动模型近来已广泛运用于地质剖面的构造演化模拟。作者以 Suppe 的断层转折褶皱的几何模型为基础,详细阐述了挤压构造区域上盘地层的几何形态变化对应的速度场分布规律及地层长度变化;编制出相应的平衡剖面正演程序,并扩充了正演程序的应用范围。以川东大池干构造为实例,制作出该构造的平衡构造演化剖面。更多还原

【Abstract】 Recently, forward kinematic modeling has been widely used in simulating structural evolution of geological sections. This paper, on the basis of Suppe’s fault-bend folding geometrical modelings, detailed the distribution of the velocity fields and the variation of the stratigraphic length corresponding to the variance of hanginghall geometry in the area with compression structure, programed the forward balanced cross section, which is also extended for wider application and ploted some diagrams of evolutions of the typical trust structure. Taking Dachigan Structure in Eastern Sichuan as an example, the balanced structure evolution is reconstructed.更多还原
