摘要
辩证地将层序地层学的基本原理应用于二连非海相沉积盆地中,利用高分辨率反射地震资料和钻井资料将白垩系划分为2个超层序和8个层序,每个层序含8～20个准层序;分析了层序界面特征及高振幅反射波与密集段的关系;总结了沉积体系和体系域特征;绘制了基准面升降曲线。
The authors attempt to use the concepts of sequence stratigraphy to nonmarine Mesozoic sediments deposited in Erlian basin. The shelf edge in nonmarine faulted basin is ambiguous at its gentle slope side, and storm base can be regarded as a reference base level for distinguishing the system tracts. 2 supersequences and 8 third-order sequences which consist of 8 to 20 parasequences have been identified in Cretaceous sediments of Erlian basin. The authors analyse the characteristics of sequence boundaries and condensed sections, summarize the characteristics of depositional systems and system tracts in space, and construct the relative change curve of the base level.
