摘要

在塔里木盆地北部的层序地层研究中，在寒武系、石炭系等许多层位的地震剖面上，发现了一系列高频前积层序。以塔里木盆地北部寒武系为例，探讨其中高频前积层序的主要特征。由于这些高频前积层序形成在相似的沉积背景条件下，故每一高频前积层序的内部结构和沉积特征基本一致。高频前积层序的发现使传统地层对比中的某些基本地色质概念需要修正，在地层对比性认识论和方法论上，得到了新的理论指导。
During the study of sequence stratigraphy in thenorthpart of Tarim Basin，a series ofhigh frequent progradational sequences have been discoveried in the seismic sections ofCambrian and Carboniferous. The main characteristics of these high frequentprogradational sequences have been discussed in this paper using the Cambrian as anexample. Because of forming on the similar depositional settings，they have similar textureand depositional character. The discovery of these high frequent progradational sequencesmakes us realize that some basic geological concepts in traditional stratigraphic correlationneed to be corrected， which gives stratigraphic correlation a new theoretic instruction incognition and methodology.
