| 摘 要： | 应用层序地层学的原理,可以将廊固凹陷的下第三系地层分为沙四段～孔店组、沙三段、沙二段～东营组三个层序。每一层序还可细分出低水期、水进期、高水期沉积体系域以及组成它们的盆底扇、斜坡扇、滑塌扇,缓慢堆积段和各种类型楔状体沉积。初步应用表明,层序地层学一般原理也适用于我国第三系陆相沉积盆地,但在应用中需作适当的修改和补充。

| Abstract: | With the use of sequence stratigraphy principle, the low Tertiary sediments in the Langgu depression can be divided into three sequences; sequence consisting of Sha-4 member and Kongdian formation,Sha-3 member sequence, and sequence of Sha-2 member and Dongying formation. Each sequence can be subdivided into lowstand, transgression and high-stand depositional system tracts which consist of basin-floor fan, slope fan,slump fan, condensed section and various progradational wedges. The preliminary application show that the general principles of sequence stratigraphy also can be applied to Tertiary continental basins in China provided that proper modification and supplement are made. |
