摘要
Integrated with field observations and analysis of fault structures this study investigated the formation mechanism and coastal evolution of Tangdao Bay in Qingdao, eastern China. The results indicate that three elements are essential for the formation of Tangdao Bay: 1) NNE-NE trending faults coutrolled the structural framework and extendsional direction; 2) Quaternary glacial erosion casted a profile that is charaterized by lowlands in the middle and high terrains on both sides; 3) Around 10 ka BP, as a large-scale transgression occurred, sea water flooded the lowlands and Tangdao Bay was formed.
