| 摘 要： | 构造物理模拟对构造反转机制分析和地震资料的构造解释和模型建立至关重要.作者在深入研究松辽盆地的基底、形成发育和改造史的基础上，对松辽盆地进行6次能再现可重复性的三维构造物理模拟，探讨了断陷盆地晚期反转变形的动态过程，表明在同一构造应力场作用下因受基底中构造边界的制约而可能产生多组方向的背斜构造带.先存的边界条件还决定了晚期变形的产状：断面缓的一侧率先变形，对应的背斜带翼部陡且褶皱幅度大；它还制约了呈雁列式展布的正断层的发育.松辽盆地不同方向的正向二级背斜构造带均为明水组沉积后（白垩纪末）同一挤压应力场作用的结果，该期反转变形控制了新生代松辽地区的沉积发育.

| Abstract: | Tectonophysical modelling plays an important role in analyzing the inversion mechanism, explaining the seismic data and establishing the tectonic model.Based on a detailed study on the basemental structures,basin evolution and reformation,the paper carried on a 3 D tectonophysical modelling of the Songliao Basin for six times,and explored a dynamic process of inversion deformation in later stage of a fault-depressing basin, which demonstrated that the anticlinal belts with multiple orientation might be created by the same stress field,constrained by the structural boundaries in the basement.In addition,the pre-existed structural boundaries could decide the occurrence of later deformation,namely,the gentle-dipping side of fault deformed first,the corresponding anticlinal belt having a steep-dipping limb,and more violent folding.Also, the pre-existed boundaries controlled developing of the en echelon normal faults.These anticlinal belts created after sedimentary period of the Mingshui Formation.In other words,the inversion of the Songliao Basin occurred in the Yanshanian movement in the latest Cretaceous, which constrained the Cenozoic sedimentation in Songliao area. |
