地质矿产部第二海洋地质调查大队

本文以珠江口盆地的实际资料为范例,提出了地震层序划分对比中容易忽略某些层序底界面的可对比性这一问题,讨论了其发生原因,阐述了为防止这一错误的发生而应采取的研究方法.

Taking the actual data collected from the Zhujiangkou (mouth of Pearl R. ) Basin in China as an example, the problem dealing with comparability of some bottom boundaries of sequence overlooked when seismic sequenee division is made is put forward. The reason given rise to the problem is discussed. Moreover, the preventive measures to avoid the problem are expounded.
