从历史的与整体的观点出发,综合了地质、地貌、地球化学与地球物理的资料,系统地研究了郯庐断裂带各阶段的形态学、运动学以及动力学机制。认为此断裂带开始形成于中、晚三叠世,其长度小于1500km,切割深度小于15~20km,此时最大左行走滑断距为430km左右。侏罗纪(208~135Ma)与中始新世-渐新世(52~23.3Ma),此断裂带表现为逆断层活动,断层面受挤压较紧闭。白垩纪-早始新世(135~52Ma),郯庐断裂呈现为略带右行走滑的正断层(走滑断距不超过100km),郯庐断裂带与其北部切割深度约为30~40km。中新世-更新世(23.3~0.73Ma)断裂带表现为带有左行走滑的正断层,走滑断距约50km,断裂带切割深度在50~80km之间。中更新世(0.73Ma以来)断裂带又变成略带右行走滑的逆断层,走滑断距不足100m。由于断裂带形成以来的剥蚀深度不大,地表的断层岩都是碎裂岩与断层泥。沿此断裂带在早白垩世构成了中国东部重要的内生金属成矿带。
From a historical and holistic point of view, we have integrated the data of geology, geomorphology, geochemistry and geophysics and systematically studied the morphological, kinematic and kinetic mechanisms at various stages of the Tan-Lu fault zone. It is considered that the fault zone started to form in the middle and late Triassic, its length is less than 1500km and the cutting depth is less than 15 ~ 20km. At this time, the maximum left-lateral strike-slip distance is about 430km. Jurassic (208-135 Ma) and middle Eocene-Oligocene (52-23.3 Ma), this fault zone is characterized by reverse faulting and the fault plane is squeezed more tightly. During the Cretaceous-Early Eocene (135-52 Ma), the Tan-Lu fault shows a normal fault with a right-lateral strike slip (the strike-slip distance of no more than 100 km). The depth of the Tan-Lu fault zone and its northern part is about 30-40 km. The Miocene-Pleistocene (23.3 ~ 0.73Ma) fault zone is characterized by a normal fault with left-lateral strike slip with a strike-slip strike of about 50 km and a depth of cut of 50-80 km. The mid-Pleistocene (since 0.73Ma) fault zone became an inversion fault with a slight right-lateral strike slip with a strike-slip distance of less than 100 m. Since the depth of denudation since the formation of the fault zone is not large, the surface fault rocks are all composed of cataclasites and fault muds. The fault zone formed an important endogenous metallogenic belt in eastern China during the Early Cretaceous.
