晚中生代期间,岩石圈的深部过程和构造应力场由左旋压扭(J2-J3)到右旋张扭(J3-K1)的反转变格导致了中国大陆东部大规模的裂陷作用,表现为广泛的火山岩喷发、花岗岩浆侵位、大规模NNE向含油气断陷盆地系和变质核杂岩的发育。根据地质和地球物理资料探讨了这期裂陷作用的运动学体制。利用计算机模拟研究了裂陷盆地的充填演化过程,结果表明边界同沉积断层沉降速率的变化是盆地发育演化的重要特征之一,并由此导致了断陷盆地的幕式扩展
During the Late Mesozoic, the deep processes and tectonic stress fields in the lithosphere resulted in large-scale rifting in the eastern part of mainland China from J2-J3 to J3-K1 Extensive volcanic eruptions, granitic magma emplacement, large-scale NNE-to-hydrocarbon rifting basin facies, and metamorphic core complexes. Based on the geological and geophysical data, the kinematic system of this period of rifting is discussed. The computer simulation was used to study the filling evolution of rifted basins. The results show that the variation of sedimentation rate of the same sedimentary boundary is one of the most important features of the basin evolution, which leads to the curtain expansion in fault basins
