The Mesozoic impact to the North China and the South China blocks in the East Asian Continental Margin by the West Pacific subduction processes and deep processes, the tectonic, magmatic mineralization and geomorphic evolutionary trends show some similarities, but there are also significant differences beween them, the dynamic mechanism is generally believed to be caused by the Paleo-Pacific Plate subduction. But how they are related is a long-term unresolved question as a conundrum and a focus of geological researches, and a huge controversy is still remained. This paper systematically summarizes the comprehensive achievements of deformation analysis, igneous geochronology, tomography and other field observations in the East Asian Continental Margin in recent decade, briefly discussing the pre-Yanshanian final assembly of blocks and the formation of the unified continental margin in China, and mainly focusing on the review of Jurassic and Cretaceous geological processes in the East Asian Ocean-Continent Connection Zone in the Yanshanian period. The temporal and spatial evolution of structural propagation, age zonation and migration of igneous rocks and huge tectono-morphological inversion in the Earth surface system, combined with deep processes are jointly to put forward: the destruction of the North China Craton was mainly affected by the westard early-stage layerred rollback, delamination and thinning of the deep lithosphere, resulting in early Yanshanian westward migrati...
