| 摘 要： | 通过系统研究郯庐断裂带两盘的构造形变和应力场，再配合断理解带内部构造研究，分析了断裂带的形成和演化过程。结果表明，断裂带经历了一次以走滑为主、两次以正断层活动为主、三次以逆断层活动为主的断裂活动，使断裂带内部结构异常复杂，形成反转构造，构成中国东部大型断裂带具有普遍意义的活动特征。

| Abstract: | According to the systematical research of the rock deformations and stress fields of the Tancheng-Lujiang fault zone and combining the research on the interior structure of fault zone the present paper analyzes the formation and evolution of the structurally complex fault zone. The study results show that the Tancheng-Lujiang fault zone experienced one stage of strike-slip faulting (in250-208 Ma),two mainly normal faulting(in 135-52Ma and 23.3-0.73 Ma),and three basically reverse faulting(in 208-135, 52-23.3,and 0.73-0 Ma).The faulting resulted in the formation of inverse structures in the fault zone and very complicate interior texture,which are the common characteristics of the macro-scale fault zone in eastern China. |
