///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.
