| 摘 要： | 鄂尔多斯盆地白垩纪古沙漠沉积地层主要为冲积扇、湖泊、河流、三角洲及沙漠沉积体系.风成沉积和沙漠沉积、风成沉积体系和沙漠沉积体系等概念有必要予以区分.基准面变化是沙漠和河流、湖泊等其他陆相地层对比的基础.鄂尔多斯盆地志丹群划分为上下两个三级层序单元,反映了两期古沙漠由风成沉积强盛期到衰退期的演化,且每个层序可划分为低位、...

| Abstract: | There are such depositional system as alluviation,aeolian,drought lake,etc,in paleo-desert depositional system in Cretaceous of Ordos Basin.It is necessary to discriminate such conception as aeolian deposition with desert deposition,aeolian depositional system with desert depositional system.Deleveling is the comparative base of desert with such continental facies as river,lake,and so on.Paleo-desert deposition of Zhidan Group in study area can be divided into two sequence unit,reflecting two stages for aeo... |
