The North Yellow Sea Basin is a Mesozoic and Cenozoic basin.Based on basin-margin facies,sedimentary thinning,size and shape of the basin and vitrinite reflectance.North Yellow Sea Basin is not a residual basin.Analysis of the development of the basin’s three structural layers,self-contained petroleum systems,boundary fault activity,migration of the Mesozoie—Cenozoic sedimentation centers, different basin structures formed during different periods,and superposition of a two-stage extended basin and one-stage depression basin,the North Yellow Sea Basin is recognized as a superimposed basin.
