| 摘 要： | 讨论了彭灌断裂带的宏观及微观变形特征。宏观构造、显微构造特征反映出该断裂带为一条脆性逆冲推覆断裂，其变形机制主要为碎裂作用。断层主要产于中生代地层之中，并有叠置的推覆岩片夹于其中，主要活动时期是在喜马拉雅期。

| Abstract: | This Paper discusses the macrostructure and microstructure of Peng-Guan fault zone. All the evidences show that thiS fault zone is a brittle thrust nappe. The brittle deformation is a very important mechanism during the thrust formed. The thrust occurs mainly in the Mesozoic strata. Some nappe sheets intercalate into it. It was active mainly during Himalayan stage. |

| Keywords: | Longmen Mountains fault zone nappe structure tectonite brittle deformation |
