RESEARCH ON THE FEATURE OF ROCK GLACIERS ON THE CENTRAL TIAN SHAN MOUNTAINS
中天山石冰川特征研究

There are several hundred rock glaciers in the studied Central Tian Shan Mts area. In the west of longitude 86 E, there are mainly Alps type rock glaciers with large scales and str-ong activities. In the area east of the line, there are Colorado type rock glaciers with small scales and weak activities. The eastern lobate rock glaciers which are "frozen throughout bot-tem" can be divided into three layers in structure. The authors consider that the cold and hu-mid conditions in the west region are the main reason to create the distributive difference of rockglacies betwwen the east and west. The factors of topography, lithology, glacier and geomorphological processes also affect the fot.nation of the difference.
