摘    要:基于现代沉积学理论和层序地层学思想,在鄂尔多斯地区晚古生代岩相古地理展布及演化特征分析基础上,对该区晚古生代地层进行精确划分、对比和层序地层学研究。进而按其沉积物特征和充填层序特点将这一时期沉积盆地厘定为三种类型,了晚石炭世本溪期至早二叠世早期(太原期)的陆表海盆地及裂陷(坳陷)盆地、早二叠世山西期近海湖盆和中、晚二叠世石盒子期和石千峰期的内陆坳陷盆地,在不同阶段的盆地中,又可划分出若干次级盆地和演化阶段。

关 键 词:层序地层学  沉积盆地  盆地构造演化  晚古生代  鄂尔多斯地区

Abstract:Based on the theories of modern sedimentology and sequence stratigraphy,the distribution and evolution of lithofacies,palaeogeography,stratgraphic division and correlation in Ordos basin during Palaeozoic are studied.Sequence stratigraphy analysis is also used to study characteristics of filling sediment in Ordos Palaeozoic basin. According to the results of study, three basin evolution stages are defined. They are epicontinental sea and rift(or down warped)basin from Benxi stage of late Carboniferous to Taiyuan stage of early Permian,offshore lake basin in Shanxi stage of early Permian as well as inland down warped basin in Shihezi and Shiqianfeng stage of middle or late Permian.
Keywords:sequence stratigraphy  sedimentary basin  tectonic evolution of basin  Late Paleozoic  Ordos area
