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。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是盆地形成的地球动力学基本机制。
The formation of sedimentary basins is closely related to the convection of heat and matter inside the Earth. It is the original driving force for the formation and evolution of sedimentary basins. The upwelling height of the asthenosphere and the location of the Moho or mantle plume are the concrete manifestations of mantle convection. Rheological boundaries within the Earth, the nature and thickness of the lithosphere, intraplate stress and sedimentation load are the basic geodynamics mechanisms of the basin.
