Based on analyses of stratigraphic succession and sedimentary characteristics of the Carboniferous-Early Permian deep-water facies in northern margin of the Dian-Qian-Gui Basin, the authors reconstruct the sedimentary history and its control factors. The stratigraphic architectures and characters suggest that sedimentary evolution of northern margin of the Dian-Qian-Gui Basin could be divided into three stages: period of intense rifting (Early Tangbaguan),period of reduced rifting (Middle Tangbaguan-Dewuan)and period of stable rifting (Late Carboniferous-Early Permian).
