Sequence-stratigraphic framework on Mesozoic and Paleogene of the East China Sea shelf basin
According to seismic wave Termination type and borehole data,4 first-class sequence boundaries and 4 second-class sequence boundaries are identifed in Mesozoic and Paleogene of the East China Sea shelf basin.Moreover, these strata into 3 tectonic sequences and 7 super sequences are divided.Based on analyzing the evolution of sequence stratigraphy,it is pointed out that the evolution of sedimentary in the East China Sea shelf basin include 6 stages;Depress stage,Fore-arc stage,Volcanic stage,Rift stage,Post-rift stage and Inversion stage.
