| 摘要: |
| The Moraines of Xibu Glacier Area in the Nyainqentanglha Range |
| The Nyainqentanglha Range moves in the NE (nearly EW) direction, and its main ridge is 6 000～7 000 m in elevation. Glacier activity was strong in Quaternary. According to Quaternary stratigraphic section, stratigraphic sequence, general geological configuration of the earth's surface and contact relationships, Three glacial epochs can be distinctly recognized in the middle part of the Nyainqentanglha Range, which are from old to young the Laqu glacial epoch Q 3,the Paranr glacial epoch Q 2～3 , and the Ningzhong glacial epoch Q 2～1 . The gravels in deposits of different glacial epochs and interglacial stages show obviously different rock characteristics, gravel forms, deposit thicknesses and weathering degrees. Discussions have also been made on such comparisons as the comparison of old glacial epoch with moraine layer, that of various interglacial stages and that of the glacial epochs in this area with those in other districts. |
