In spite of tectonic-plate environments surrounding the Chinese continent having no obvious variation in the recent about 40 Ma, the tectonic activities in the eastern North China Craton in the Neogene showed obvious difference with those in Paleogene. The slab evolution showed some temporal consistence with the tectonic activities in eastern North China, and also with the oft-com:office:smarttags" />Japan Sea opening. Furthermore, the possible effects acted on the overlying lithosphere by the slab in different stages could interpret the tectonic events mentioned above. Thus, the bottom-up effects attributed to the Pacific subduction mainly controlled the evolution of eastern North China in the Cenozoic, and they are also the dominant factors controlling the dynamics of North China even in the horizontal during about 8~23 Ma.oft-com:office:office" />
