STUDY ON THE QUATERNARY GLACIAL RELICS IN QINHUANGDAO AREA, HEBEI PROVINCE

As the discovered glacial relics are mostly scattered and isolated, with multi-interpretation, which cannot fully support the existence of glaciers, the topic whether the Quaternary glaciers exist in the low and middle mountains of eastern China has been controversial for nearly a century. Through the long-term detailed investigation in Qinhuangdao section of Yanshan Mountains, a large number of relics related to glaciers have been found, the main types including glacial boulder, moraine, stone sea, moulin, cirque, glacial trough, glacial striation, sheepback rock, pyramidal peak and U-shaped valley. These relics are all interrelated and form strong evidence group and chain, which provide reliable data for the study of Quaternary glaciation in eastern China.
