摘要：

文中通过对晚石炭世至早三叠世华南和华北地块古地理特征以及地层学证据的分析，认为中国东部的郯庐断裂带自海西期以来经历了两个主要发展阶段：第一阶段是广义的郯庐断裂带发展阶段，在海西期它是扬子地块北东缘呈宽缓弧形展布的边缘裂陷槽(或盆地)的边界；在印支期由于扬子地块与华北地块的碰撞，成为两地块的对接边界，具有逆冲推覆的性质，属广义的特提斯构造域。第二发展阶段从燕山期以来，发展成为一条平移断裂带，属于狭义的环太平洋构造域的平移系统。自晚石炭世至早三叠世的中国南方及华北东南部的岩相古地理资料显示了扬子地块与华北地块的对接始于晚二叠世早期，地块的抬升自南向北、自南东向北西方向呈迁移趋势；印支期的郯庐断裂带是一条北东、北北东展布的缓‘S’形的地块拼贴边界，在现今的郯庐断裂带上表现为残留的由北北西向南南东的斜向逆冲推覆的性质，表现为大别苏鲁造山带的中上部构造层的变形，即张八岭构造带及前陆褶皱冲断带的变形；燕山期以来则为众所周知的狭义的郯庐断裂带即郯庐平移断裂系统的一部分。

Abstract:

Based on analyzing lithofacies palaeogeography andstratigraphy from the Carboniferous to Triassic of North China Block and South China Block in easternChina，the TanLu Fault Zone can be divided into two main development stages since the HercynianFirst stage is a fault zone in broad senseIt is a boundary of a rifted cratonic margin (or basin) that spreads in a wide arcshape along the northeastern margin of the Yangtze Block during the Hercynian It is a collision suture between the Yangtze Block and North China Block during the Indosinian period，a thrustnapping fault zone belonging to the Tethyan regimes in broad sense Second stage isa wrench fault system，which belongs to the Pacific Ocean cycle regime in narrow sense during the Yanshanian and Himalayan periodsBased on analysis of the lithofacies palaeogeography from the Late Carboniferous to the Early Triassic，the collision between the YangtzeBlock and North China Block started in the early age of the Late Permian The lifting time of the Yangtze Block started from south to north or from southeast to northwest in directionThe TanLu Fault Zone was a “S”shaped border trending northeast or northnortheast as a suture of the blocks collision It is a thrustnapping zone from NNW to SSE The tectonic deformation of the suture was shown as the Zhangbaling structural belt and the foreland foldingthrusting belt that belongs to the midupper tectonic layer of the DabieSulu orogenic belt
