| 摘 要： | 通过对东营凹陷牛庄洼陷沙三段上亚段和沙二段地层沉积体系的划分以及沉积体系与层序格架之间关系的研究,发现在断陷湖盆的萎缩期也可以发育大型浅水三角洲,与坳陷型湖盆浅水三角洲不同的是,它的主要的沉积微相类型、平面形态和砂体展布特征等具有明显阶段性的变化,并且该变化与湖盆体系域的演化有着密切联系.在低位和湖退体系域,三角洲主要... |

| Abstract: | A large shallow-water delta was found in the rifting lacustrine basins based on the study of depositional systems,sedimentary characters and sedimentary model of Upper of the 3rd and the 2nd Member of Shahejie Formation,Paleogene in the Niuzhuang subsag,Dongying sag.Different from the shallow-water deltas formed in rifting lacustrine basins,it has its own major depositional microfacies type,plane features,and distribution pattern,which all display distinct phase changes closely related to the evolution of l... |
| Keywords: | shallow-water delta rift lacustrine basins Niuzhuang subsag depositional model |
