陆相层序地层学应用中几个问题的讨论

层序地层学提出了一个等时地层对比的概念,即在等时框架下进行地层对比,使得地层对比更具有实际的地质意义。随着陆相沉积盆地研究中层序地层学的引入,在国内引起了一些颇有争议的问题。本文就层序地层学理论在陆相沉积盆地研究中的适应性问题、陆相层序成因和具体研究工作方法问题等作了有益的探讨,旨在促进国内陆相层序地层学的发展。

DISCUSSION ON SOME QUESTIONS IN THE APPLICATION OF CONTINENTAL SEQUENCE STRATIGRAPHY

Sequence Stratigraphy presents a concept of isochronostratigraphic correlation,that is,stratigraphic correlation under an isochronous framework.This makes stratigraphic correlation have more practical geological meanings.With the introduction of Sequence Stratigraphy into the study of continental sedimentary basins,some controversial questions arose in our country.Aimed at promoting the development of continental Sequence Stratigraphy in China, this paper gives a helpful discussion on the adaptability of Sequence Stratigraphy theory in the study of continental sedimentary basins,the genesis of continental sequences,the specific methods of research etc.
