摘    要:郯庐断裂带的成生演化与含超高压变质带(UHP)的大别及苏鲁造山带存在较密切的时空关系。郯庐断裂带所在的构造位置应是晚二叠世华北与扬子地块碰撞时的根带。UHP岩石的折返过程可能发生于华北、扬子地块的大角度旋转、拼合过程中。在华北与扬子地块的造山后期或者造山期后的构造变形中所记录的构造形迹经晚中生代以来的中国东部构造变形叠加而逐渐呈现复杂的构造组合,所谓“郯庐断裂带”的走滑平移即其中的一种运动方式。华北与扬子地块碰撞造山作用与陆内变形最终造就了大别—郯庐—苏鲁复合造山带。

关 键 词:大别—郯庐—苏鲁复合造山带  旋转拼合  郯庐断裂带  碰撞造山作用

Abstract:The formation and evolution of the Tancheng Lujiang fault has close spatial temporal relationship with the Dabie Sulu UHP bearing orogen.The tectonic setting of the Tancheng Lujiang fault is located at the root zone of the collision between north and south China blocks which took place in the Early Permian time.The collision is characterized by the process of large scale rotation and amalgamation, in which exhumation of the UHP rocks might happen.The deformational record of the late orogeny and/or post orogeny which was reworked by late Mesozoic deformation in south China presents complicated structural assemblage, among which the strike slip faulting of the Tancheng Lujiang fault is considerable.The collisional orogenesis between north and south China blocks and intra continental deformation finally led to the formation of the multiple Dabie Tanlu Sulu orogen.
Keywords:Multiple Dabie  Tanlu  Sulu orogen  Rotation and amalgamation  Tancheng  Lujiang fault  Collisional orogenesis
