Abstract: Key tectonic changes in superimposed basins can be classified as uplifted and eroded change, continental-oceanic transform change and thrust-fold change, and the several control factors for them include transform of tectonic stress field transform, change of deep dynamic procedure and transform of deep thermal system, etc. Such changes make superimposed basins have distinct features of staging differential tectonic deformation. The main features of those basins in China are as follows: uplifting and eroding in Caledonian stage, uplifting-eroding and thrust-fold in Hercynian stage, continental-oceanic transform in Hercynian and Indosinian stages, thrust-fold in Yanshan and Himalayan stages, with manifestations of migration and superimposition in structural deformation, variation of basin structure, formation of regional unconformity, migration, compression, extension and transform of basin boundary as well as change of basin-mountain framework, etc.

Key words: superimposed basin, key tectonic change, staging differential tectonic deformation, structural deformation and superimposition, structural transition
