摘　　要：在华北陆块区进行构造-地层区划的基础上,对华北陆块中元古代-新元古代、早古生代、晚古生代、三叠纪-早侏罗世、中侏罗世-白垩纪5个大地构造阶段不同构造-地层区内的沉积盆地类型、充填序列和时空演化过程进行了分析、讨论.中-新元古代是华北周缘裂谷发育期.寒武纪-早、中奥陶世,华北广泛发生沉降并接受海侵,形成几乎广布全华北的碳酸盐岩台地.晚奥陶世-泥盆纪,华北整体抬升,遭受剥蚀,沉积缺失.石炭纪-二叠纪,华北陆块再次发生沉降并接受海侵,形成广阔的陆表海海陆交互相沉积,至晚二叠世华北陆块进入陆相盆地发展阶段.中生代,华北陆块陆内构造运动活跃,普遍形成与火山活动相伴的断陷盆地、坳陷盆地和拉分盆地.On the basis of divisions of tectonic-stratum of the North China block （NCB） area, this article discusses the type of sedimentary basins formation region, filling sequence and temporal evolution of different tectonic-stratum zones for each construction phase according to five tectonic stages as Mesoproterozoic-Neoproterozoic, Paleozoic, Late Paleozoic, Triassic-Early Jurassic, Middle Jurassic-Cretaceous. Meso-Neoproterozoic is the stage of development of periphery rifting. Cambrian-Early, Middle Ordovician, North China plate synchronized global settlement and received extensive transgression, forming widespread carbonate platform of almost all north China. Late Ordovician-Devonian, NCB overall uplift and erosion, sedimentation is missing. Carboniferous-Permian, North China block subsided again and suffered transgression, forming a broad epicontinental sea paralic deposition. To Late Permian, NCB entered the stage of continental basin development. Mesozoic, continental tectonic activities were active, forming fault basins, sag basins and pull-apart basins broadly.
