| 摘 要： | 早白垩世周口坳陷谭庄沈丘凹陷接受了商水期、永丰期和巴村期的一套陆相湖盆沉积,主要沉积相类型有冲积扇相、扇三角洲相、滨浅湖相和较深湖相。这套地层可以划分3个层序,构成一个构造层序。湖平面的升降变化直接控制了层序的形成和发育。层序的演变反映出本区经历了3次湖平面的升降,同时反映出构造对层序变化的控制。 |
| 关 键 词： | 谭庄沈丘凹陷 早白垩世 沉积相类型 层序地层 |

| Abstract: | Early Cretaceous terrestrial lake sediments of Zhoukou Sag mostly deposited in Tanzhuang-Shenqiu depression during the stages of Shangshui, Yongfeng and Bacun.The main sedimentary facies can be recognized including alluvial fan,fan delta,shallow lacustrine and deep lacustrine.It is divided into three sequences,being a supper sequence controlled by tectonics.The development of those sequences was controlled directly by lake level variation.Evolution of the sequences reflects that the area had gone through three lake level changes,and tectonics controlled the sequence changes. |
| Keywords: | Tanzhuang-Shengqiu depression Early Cretaceous types of sedimentary facies sequence straigraphy |
