Description :
Limestone pinnacles on mountain slopes in Tibet were measured for morphological analysis and the results were compared with those from tropical towers and cones on karst mountain slopes of Shuicheng, southwest China. The morphological structure and orientation analyses show that pinnacle development is largely controlled by lithological and stratigraphic conditions. Further analysis indicates that Tibetan limestone pinnacles were formed by strong physical weathering under periglacial conditions. Four kinds of morphogenesis of the pinnacles are suggested.
