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。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。
Abstract
The formation of sedimentary basin is mainly related to the thermal and material convection of the earth interior,and that is the primary driving force causing the formation of sedimentary basin.The rise of the asthenosphere,the position of Moho and mantle plume are the indication of the mantle convection.The rheology boundary within the mantle lithosphere,the nature of the lithosphere,the intraplate stress and thickness,the sedimentary loading are the important geodynamic factors of sedimentary basin.
