| 摘要: |
| A Preliminary Discussion on Features and Dynamics of Sequence Deformation in South China and Neighboring Areas |
| From the east of Longmen Mountain fault belt to the west of Xuefeng Mountain fault belt,the structural deformation is well regulated. Structural features, such as faults and folds, are mostly arranged in NE direction, and their deformation intensity weakens from SE to NW in this region. This regulated deformation is considerable in scale, and hence the partition wall style fold-thrust belt in the east of Sichuan is much bigger than the famous Jurassic style folding. The regulated deformation is intimately related to the multi level substrata decollement that inclines southeastward in basement. Such deformation occurred during early Indochina Yanshanian period, and took shape during late Yanshanian Himalayan period, and its dynamic force might have come from the South China plate which moved from SE to NW. |
