| 摘要: |
| 沈家营地区的下侏罗统武昌组下段为一典型的曲流河沉积体系,可识别出河底滞留沉积相、曲流沙坝沉积相、天然堤沉积相、洪泛盆地沉积相和越岸扇沉积相。笔者根据沉积相的分布特征,对该区的水动力条件及古地理特征作了详细的分析。 |

| Abstract: |
| The lower member of the Lower Jurassic Wuchang Formation in the Shenjiaying region,Huangshi,Hubei represents a typical depositional system of meandering streams,and may be divided into five sedimentary facies:river-bed lag deposits,meandering bar,natural levee,flood basin and overbank fan.The hydrodynamic conditions and palaeogeographic features are discussed in detail in the present paper on the basis of sedimentary facies distribution. |
