采用单因素分析综合作图法，结合大地构造和单剖面相分析，从定量化角度对鄂尔多斯盆地早休罗世富县组岩相古地理进行了研究，认为三叠纪末印支运动使鄂尔多斯盆地抬升，遭受剥蚀，形成起伏不平地势。侏罗纪早期，在相对低凹地区接受沉积，形成了以剥蚀一残积相为主体，冲积、湖沼相为辅的古地理景观，在这一背景上，大面积发育了中休罗世沉积。 Based on the comprehensive mapping of single factor analysis and the analysis of geotectonic and single-section facies, the lithofacies-paleogeography of Lhasi Fuxian Formation in Early Ordos Basin was studied quantitatively. It is concluded that the Indosinian movement at the end of Triassic period resulted in uplifting of Ordos Basin , Suffered erosion, the formation of rough terrain. In the early Jurassic, sediments were accepted in relatively low-lying areas, forming paleogeographical landscapes dominated by denudation-sedimentary facies, supplemented by alluvial and lacustrine facies, and on this background, large-scale development of the Neolithic sediments.
