庐山冰川地貌释疑

ON THE GLACIAL LANDFORMS IN LU SHAN

The authors propose the following arguments: 1) Da Ao is really cirque. Its landform was not crcated by periglacial snow erosion or solifluction; nor water flow. 2) "U" shaped valley of Wang Jia Po is a glacial trough. It was not formed from water flow or weathering under the control of the structure or nature of the uocks. 3) Ridges and hill locks in the mountain foot are the end moraine bars, not the "isolated islands" piled by the mudflow. 4) The climate of Lu Shau in the glacial stage was the cold one which could cause the glacier. wet and hot climate exists in the interglacial stage, not in the glacial stage.
