摘要: 基于笔者多年对鄂尔多斯盆地及周缘地区晚古生代研究成果,结合野外剖面实测、钻井资料分析、地层学与层序地层学、地球化学、年代学等研究结果,从岩性特征、地层厚度、地层接触关系、物源分析、沉积相类型多方面进行对比研究,认为鄂尔多斯盆地及周缘地区上古生界是华北地台的一部分,因此,其沉积充填及沉积演化研究必须置于晚古生代大华北盆地之中。在此研究基础上绘制了晚古生代各组鄂尔多斯盆地及周缘沉积相平面展布图,亮点是向东部和南部进行了扩张,并详述了晚古生代沉积演化过程,为该时期华北地台原始沉积面貌的恢复提供了新的依据。

Abstract: Based on the detailed studies of the late Paleozoic in the Ordos Area for decades,including field measurements,stratigraphy and sequence stratigraphy,geochemistry and geochronology studies,the authors have analyzed lithological characteristics,stratum thickness,stratum contact relationship,sediment provenance and sedimentary facies types. We propose that the Ordos area during the late Paleozoic is a part of the North China Platform. Based on this study,all stages of late Paleozoic sedimentary facies map of the Great Ordos Area was drawn. These maps extended the eastern and southern part of the original Ordos Area,which provided a new evidence for the restoration of the original sedimentary features of the North China Platform in this period.

Key words: Ordos Basin, late Paleozoic, sequence stratigraphy, sedimentary facies, Sedimentary evolution
