Abstract:In this paper, the characteristics of the Quaternary glacial moraine and related relics found in Mount Mengshan, Shandong Province, are systematically introduced. The authors concentrate mainly on the moraines, scratches, polished surface and chatter marks distributed in Lanxi valley. At the same time, the distribution, size, composition and rock characteristics of the lateral moraines and felsenmeers are reported. Based on the distribution of the lateral moraine and the weathering degree of gravels, we are trying to identify the moraine traces as the product formed at the last glacial period. Based on measurement and statistical analysis of the scratches on the polished bedrock surface from both sides of the valley, the length/width ratio of scratches on valley walls is about 10:1. Using lateral moraine maximum height method and investigation with lateral moraine at Mount Mengshan region, we have estimated the height of the last glaciation snow line in the southern slope of Mount Mengshan. It is about 700 meters.
