河流、沙漠与湖泊沉积环境下形成的层序的对比分析

Correlation Analysis on Sequence Formed under the Environment of Fluvial,Desert and Lacustrine Depositions

从不同陆相环境下各种层序地层的发育特征分析入手,探讨了不同类型层序地层———沙漠、河流、湖泊层序地层对比的基础和内容。认为不同陆相环境下各种层序的对比基础是基准面变化,对比内容包括层序的界面特征、层序结构即体系域构成和体系域内沉积体系发育特征,讨论了不同陆相沉积环境下发育的层序地层对比存在的一些问题。

Based on the analysis of growing characteristics of strata under different depositional environments,the foundation and content of contrast for different sequence stratigraphies,such as desert,fluvial and lacustrine sequence stratigraphies.It is considered that the foundation of correlation is the base level change under different continental depositional environments, its content includes the characteristics of sequence interface,its structure,that is the characteristics of the system formation and depositional development in the system.Also the problems existed in the correlation of sequence stratigraphy grown under different continental depositional environments are discussed.
