| 摘 要： | 通过分析钻孔和浅地层剖面资料,研究了胶州湾及青岛前海潮流沉积体系。该体系包括大沽河-洋河潮控三角洲和与狭口海湾密切相关的涨、落潮流三角洲,潮流作用在各三角洲的形成过程中为主要的沉积动力。前者发育在湾西侧,形成了河口沙坝和分流间湾等沉积相;后者分布在湾口两侧,以潮道和潮流沙脊为主要特征。根据对各沉积相特征的分析,认为潮流沉积体系的演化已整体趋于稳定。 |
| 关 键 词： | 潮流沉积体系 潮控三角洲 涨、落潮流三角洲 潮流沙脊 胶州湾 |

| Abstract: | Based on an analysis of drill and stratigraphy profiles,the tital depositional system in the Qingdao area is studied.The Dagu-Yanghe tidal delta,a facies system,is formed on the west side of Jiaozhou bay,where the river mouth bar and interdistributory bay are the major sub-facies.The flood-tidal delta and ebb-tidal delta are in close proximity of the inlet.Tidal channel and tidal sand ridge facies is the dominant facies of the tidal-delta.The formation of the system is governed primarily by tidal-current processes.It is concludesd that the evolution of the depositional system is becoming steady,and its development depends on sea-level changes in the future. |
| Keywords: | tidal depositional system tidal delta flood and ebb tidal delta tidal sand ridge Jiaozhou Bay |
