| 摘 要： | 大陆深俯冲与快速折返假说提出20年来一直存在争论.大陆深俯冲中需要地幔对流拖拽,但存在大陆根的事实和30亿年中在上地幔固定深度缓慢生长的大颗粒金刚石实物证据,表明地幔并未发生大规模对流.目前大地构造学的主流理论本质上是"热机类理论",地幔热对流是这部热机的驱动原动力.对地幔对流的质疑表明,摆脱"热机类理论"的束缚,开展...

| Abstract: | The hypothesis of continental deep subduction and rapid exhumation has been of much controversy,since it was put forward two decades ago.It is known that the continental deep subduction needs mantle convection to drag,but the fact of observed continental roots and the physical evidence of slow growth of large diamond particles at fixed depth during three billion years in the upper mantle suggest no occurrence of a large-scale mantle convection.The mainstream current tectonic theory is essentially a heat eng... |
