摘　　要：华北板块东部印支和燕山期构造演化差异、盆地分布格局变迁及其空间叠合关系是中国东部构造变化的结果。中生代期间 ,郯庐断裂带应对应依兰—舒兰断裂带 ,它们与兰考—聊城—盐山 -台安—大洼 -敦化 -密山断裂带呈共轭关系。两断裂带将华北板块东部分割为多个三角块体 ,三角块体的构造演化与陆内壳下拆沉和壳内挤出逃逸构造有关 ,并控制了华北东部燕山期高原隆升及岩石圈减薄。Tectonic transition in the east of China resulted in a distinct difference between Indosinian and Yanshanian tectonic evolutions, and also their stacking and distribution patterns in space and time of basins in the North China plate. During Mesozoic, the Tan-Lu fault system may correspond to the Yilan-Shulan fault system. They conjugated with the Lankao-Liaocheng-Yanshan -Tai’an-Dawa-Dunhua-Mishan fault system. The eastern North China plate is subdivided by these fault systems into several triangle blocks. The tectonic evolution of these triangle blocks in the east of the North China plate was related to both sub-crustal delamination and intra-crustal extrusion or escape tectonics. The authors also discuss the uplifting of the Yanshanian Plateau and the related lithospheric thinning in the east of North China, the Tan-Lu left-lateral strike-slip fault, the mirrored basin distribution by the both sides of this fault, and the coexisting of compressional and extensional basins.
