Glacial Environment and Sedimentary Processes of End Moraine Since Last Ice-Age at the Headwater of the Urumqi River, Tianshan

Feng Zhaodong and Qin Dahe (Department of Geology and Geography, Lanzhou University)  
An attempt was made to discuss the characteristics of various end moraines based on the theory of geomorphology and principle of depositional dynamics. Glacial environment and sedimentary processes were treated in the light of depositional characteristics. Till fabric, structure, grain-size and boulder shape were analysed to verify the hypothesis and achieve informations of glaciers. The concept of the dispersion of the moraines, the tendency of till fabric and the average inclining angle of boulders was set up on the works of former writers and our own data for furthering study, correcting contour density diagram, and describing qualtatively relief. By analysing the depositional informations in the headwater of Urumqi River, we concluded that Wangfeng glacier was a transitionary one during last glaciation. The temperature rose quickly during deglaciation time.
