| 摘 要： | 利用高分辨率层序地层学方法,以延水河剖面研究为重点,详细剖析了中侏罗统延安组不同级次基准面旋回划分,建立了鄂尔多斯盆地延安地区延安组高分辨率层序地层格架。共识别出了36个短期、8个中期和3个长期基准面旋回。讨论了不同级次基准面旋回叠加式样与沉积相、沉积作用和构造作用等的响应关系,进一步通过基准面旋回层序研究了盆地的充填演化史。

| Abstract: | On the basis of high-resolution sequence stratigraphy,the detailed study on the subdivision of different orders of the base-level cycles in middle Jurassic Yanan Formation has been performed in Yanshui river cross section,and a corresponding high-resolution sequence framework has been established in the middle part of Ordos Basin.There can be recognized 34 short,8 middle and 3 long base-level cycles.Simultaneously,the paper has also discussed the relationship between the stacking patterns of different cycles and sedimentary facies,deposition and tectonics,and furthermore,investigated the basinal filling history by the base-level cycle sequences. |
