| 摘 要： | 泌阳断陷陆相层序外部构型研究包括层序级别的厘定与划分以及界面的类型及其识别标志。陆相层序构成单元可分为８个级别，前４级属低频层序，后４级为高频层序。泌阳断陷湖盆的３类盆地原型，分别形成了３套盆地充填序列及其所对应的３个构造层序（Ⅰ，Ⅱ，Ⅲ）；构造层序Ⅱ为该断陷湖盆的沉积充填主体，可进一步划分为７个层序组，其中在层序组ⅡＤ（即核三段上）中可识别出３个层序。陆相层序的体系域具四分性：低水位体系域、水进体系域、高水位体系域及水退体系域；小层序组有４种基本类型：进积小层序组、低位加积小层序组、退积小层序组和高位加积小层序组。

| Abstract: | The study on the outer configuration of terrigenous sequence in Biyang fault depression includes sequence classification and boundary identification. Terrigenous sequences can be classified into eight grades, and the former four are low frequency sequences, the others are high frequency sequences. The three kinds of prototype basins formed three basin fill sequences respectively and responding tectonic sequences. Tectonic sequence Ⅱ, a major depositional body in this fault depressed lacustrine basin, can be further classified into seven sequence sets in which sequence set Ⅱ D, meaning the upper member of E h 3, includes three sequences. Terrigenous sequence is characterized by four parts: lowstand system tract, transgressive system tract, highstand system tract and regressive system tract, and parasequence sets have four basic types: progradation, lowstand aggradation, regression and highstand aggradation. |
