摘要
沉积盆地的形成主要与地球内部的热和物质的对流密切相关，它是沉积盆地形成和演化的原始动力。软流圈上涌高度，莫霍面或地幔羽的位置是地幔对流的具体的表现。根据地球内部流变学界限，岩石圈的性质和厚度，板内应力和沉积负荷可以将原始盆地划分为克拉通盆地，拉张盆地，挤压盆地和走滑盆地。
The formation of sedimentary basins is considered to be closely related to the thermal and material convection in the Earth's interior.The mantle convection is the primary driv- ing force for the formation and evolution of sedimentary basins,and manifested in the posi- tion of the asthenosphere,Moho discontinuity and mantle plume.The ancestrial basins have been classified,in this paper,into cratonic,extensional,compressional and strike-slip basins according to the rheologic boundary within the mantle lithosphere,the nature and thickness of the lithospere,intraplate stress,and sedimentary loading.
