| 摘要: |
| 通过详细的地震剖面解释,结合川西前陆盆地演化史,阐明莲花山地区地下断层及褶皱的几何形态及特征。认为区内部分断层是继承先成断层发育而来,部分断层是喜马拉雅期运动的产物;部分断层存在断层反转现象;控制盆地内沉积的主要因素是几个大断层。 |

| Abstract: |
| The geometry and features of the subsurface faults and folds in the Lianhuashan area are discussed on the basis of the interpretation of the seismic profiles in integration with the evolution of western Sichuan foreland basin. Major faults in this area were evolved from the antecedent faults during the Himalayan orogeny. Some of the faults are overturned. The deposition in the basin is directly constrained by these faults. |
