Abstract: Since the 1980s, the Holocene clinoform or the mud wedge around the Shandong Peninsula has raised great attention from marine geologists, and many papers have been devoted to this topic. In this paper, we made a review of the previous research results and published papers. The prevailing opinion believes that the wedge-like sedimentary body, which is thicker in the middle and becomes thinner on the two sides towards the land and sea, is formed under the interaction of the yellow sea warm current and the yellow sea coastal current around the Shandong peninsula. The sediments are mainly from the Yellow River. The formation mechanism of the deposits involves many factors, such as the tide, sea level rising and the shifting of the Yellow River mouth. It was formed in the period of Late Holocene deglaciation when the sea level was rising. We also discussed the problems remained. It is suggested that further researches should pay more attention to the marine sediment dynamics, and the transportation and sedimentation of the fine sediments under the hydrodynamic regime..
