| 摘 要： | 中国东部陆缘中区中-新生代深大断裂十分发育.根据断裂的时空分布规律,可划分出4个断裂系:燕山造山带断裂系、秦岭-大别-苏鲁造山带断裂系、郯庐断裂系及东海陆架盆地-冲绳海槽断裂系.4个断裂系具有各自不同的断裂迁移规律:燕山造山带印支-燕山期断裂具有从早至晚从EW→NE→NNE向偏转迁移规律;秦岭-大别造山带北麓逆冲推覆作用的强度在印支-燕山早期表现出南强北弱、东强西弱和东断西褶趋势,同时具有由东向西由早到晚穿时迁移演化特征,燕山末期-喜山早期则相反,表现出北强南弱、西强东弱的构造特征;郯庐断裂系的活动对盆地的控制作用具有由早到晚由西向东、由南向北迁移规律;东海陆架盆地-冲绳海槽断裂的形成时代具有明显的从西向东越来越新的迁移规律.4个断裂系及构造迁移规律分别是板块碰撞-陆内俯冲、陆内造山、走滑、板块俯冲后退4种不同地球动力学背景中的产物.

| Abstract: | Deep and large faults developed very well in the central section of epicontinent of the East China. Based on the space-time distribution of the faults, four fault systems are divided, namely, Yanshan orogenic belt fault system, Qinling-Dabie-Sulu orogenic belt fault system, Tanlu fault system and East China Sea shelf basin-Okinawa trough fault system. The four fault systems have different migration regularities of the faults. The faults of Indosinian epoch-Yanshan epoch of Yanshan orogenic belt have deflective migration regularity from EW direction to NE direction to NNE direction from the early to the late periods. The strength of thrust-nappe of the Qinling-Dabie orogenic belt fault system shows a tendency of being strong in the south and in the east, weak in the north and in the west and of faulting in the east and folding in the west in Indosinian-early Yanshan epochs. Meanwhile,the faults have the feature of diachronous migration evolution from the east to the west from the early to the late periods.On the contrary, the last Yanshanian - early Himalayaian epochs show the tectonic feature of being strong in the north and in the west ,weak in the south and in the east. The activity and basin-controlling function of the Talu fault system are characterized by the migration from south to north from early to late periods. The formation time of the East China Sea shelf basin-Okinawa trough fault system become apparently younger from west to east. The four fault systems and their structural migration are the products of different geodynamic backgrounds; collision of plates, intracontinental subduction, intracon- tinental orogency, strike-slip, plate subduction and retreat. |
