摘要：

四川盆地的震旦系至第三系可划分为3个巨层序、17个超层序。超层序的周期平均为37Ma。巨层序边界的形成与太平洋板块和华南板块的聚合有关,超层序边界在区域上可以追踪、对比,它们大多数与区域构造运动相对应。

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.
