塔里木盆地北部古生代层序地层系统
|
摘要
层序地层系统,本质上就是以各种不同级次的海平面变化所控制的不同级次的沉积层序为单位,在年代地层学格架中所建立起来的地层系统。本文以露头剖面的层序地层研究为主要依据,结合生物地层和地震地层的研究成果,在进行详细层序划分的基础上,在塔里木盆地北部古生代地层中建立起了由不同周期叠加的海平面变化所控制的不同级次的层序所组成的层序地层系统。通过生物地层和层序地层相结合的方法,厘定并标定了一系列重要地质界线的年龄,提高了该区地层划分的精度。
Sequence stratigraphic system is a stratigraphic system constructed in the chronostrati-graphic framework. The construction of this system depends on the depositional sequences with different ranks which are controlled by corresponding sea-level changes. Such a sequence strati-graphic system has been constructed for the first time in the Paleozoic strata in the northern part of the Tarim basin, which mainly depends on the study of outcrop sequence stratigraphy combined with the results of seismic stratigraphy and biostratigraphy. The system is composed of different ranks of sequences controlled by sea-level changes occurring in different periods, which enhances the precision of division and correlation of strata in the northern Tarim basin.
