///In this paper, the author divided the Mesozoic-Cenozoic in East China into six tectonic-sedimentary cycles. The movement occurred in Late Jurassic was a style-changed movement. In addition, the author further divided the tectonic deformation history of the region into two deformation phases (T-J) and one transitional phase (K₁). During the two deformation phases, two types of basins and two tectonic systems developed. There exists extensive tectonic unconformity, which shows that the duel structures are basic characteristics of Mesozoic-Cenozoic geotectonics in East China.
