摘　　要：在全球范围内流行的按密度差、温度差建立的地幔对流、拆沉作用和地幔柱(羽 )理论 ,阐明不了中国大陆岩石圈、大陆造山带的组成、结构与演化。从我们对中国秦岭及西部造山带的研究中 ,发现和提出的在地球自转速度变化制约下的多层扭动涡旋甩出说——核幔壳“风暴”所引发的热核反应是地球发展与演化唯一的、统一的“动力”来源 ,是中国大陆岩石圈、大陆造山带形成。The currently prevalent hypothesis such as mantle convection, delimination and underplating of lithosphere, and mantle prism based on the difference in density and temperature could not reasonably explain the composition, structure and evolution of the lithosphere and continental orogrnic belt in China. On the basis of long term research work in Qinling and other orogenic belts in western China, the authors consider that the theory of multiple layer twisting vortex and throw out, or ″typhoon″ (or storm) of crust and mantle (or core) controlled by changes in the velocity of the earth's rotation is the only and universal source of dynamics. It is also the theory for the dynamics of the formation, development and evolution of continental lithosphere and orogenic belt of China.
