Abstract:

Based on the analysis of regional seismic lines,well logs and outcrops,3 megasequences and 17 super seismic sequences have been recognized.The period of supersequence is about 37 Ma.The formation of megasequence boundaries was related to the convergence between Pacific Plate and South China Plate.Supersequence boundaries could be traced and correlated regionally,most of them correspond with tectonics.
