This paper reports the discovery of chatter marks on the glaciated bedrock in Lushan, Mt. Shandong Province, East China. The authors analyzed the mechanism of chatter marks and believe that chatter marks are a series of en echelon R-shear fractures on the bedrock surface. Chatter marks are not only the direct evidences of ice moving over the bedrock, and can show the moving direction of the former disappeared glacier. Apart from chatter marks found in Lushan Mt., there are other related landform evidences, such as, giant erratics, lateral moraines, potholes and scour grooves or troughs, showing the existence of Quaternary glaciation in the East China.
