饶阳凹陷下第三系层序类型及发育模式
|
摘要
根据陆相地层层序在地震剖面、电测曲线上的识别标志、岩石类型组合特点以及古生物等方面的特征,将饶阳凹陷在下第三系划分出了三个二级层序、十个三级层序。其中层序Ⅰ、Ⅱ为裂谷初始期湖泊层序,层序Ⅲ、Ⅳ、Ⅴ为裂谷强活动期湖泊层序,层序Ⅵ为气候层序,层序Ⅷ、Ⅸ、Ⅹ为河流层序。其中裂谷期湖泊层序可以划分为三个体系域,即低位域、湖侵域和高位域,而河流层序可划分为基准面上升体系域和基准面下降体系域,针对研究区目的层段所划分层序发育的特点,在层序地层单元划分和对比的基础上,对不同层序类型层序的发育模式进行了总结。
Based on the identification of continental sequence on seismic section and well-logging curve and the characteristics of rocks′ combination and paleontology, the strata of Eogene in Raoyang Depression are divided into three second-order sequences and ten third-order sequences. Third-order sequencesⅠ,Ⅱ,Ⅲ,Ⅳ,Ⅴ,Ⅵ,Ⅶ are rift lacustrine basin sequence, and can be divided into three system tracts, that is low stand system tracts, lacustrine transgressive system tracts and high stand system tracts. Third-order sequencesⅧ, Ⅸ, Ⅹare fluvial sequence, which can be divided into base level rising system tract and base level falling system tract. Based on the identification and correlation of sequence stratigraphic units, sequence stratigraphy models are established. A primary research on relationship between sequence stratigraphic model has been done.
