| Abstract: | The Taibaishan (3767 m), situated in the Mixian, Shaxi Province, is the highest peak of the Qinling Mts, where some glacial lakes and glacial troughs formed during the Quaternary.The following are their characteristics:1. The glacial troughs display cross pattern on the horizontal plane.2. The E-W trending trough exhibits a wide valley in the transverse section, while the N-S trending trough exhibits U-shape.3. The E-W trending trough is gentle in the longitudinal profile, while the N-S trending trough is stepwise with many scarps crossed the faults.4. The cirque always developed at the junction of faulting belts.5. Cirques are small in area and large in depth. Some glacial lakes had specific geometrical form.It is noted that the glacial relief developed in the Taibaishan area is associated with faulting tectonics. The glacial relief can be mostly explained by,tectonics. The fault fracture zone is favourable to glacier plucking. |
