郯庐断裂带是世界上最大的大陆走滑断裂带之一，其左旋位移长达数百公里。本文评述了该断裂带的四种构造模式：（1）陆内穿流断裂，（2）缝合线，（3）陆内转换断裂，（4）碰撞压痕。我们认为，郯庐断裂带是一条发育在西北环太平洋边缘内陆侧的大型横推断裂。这一结论是基于断裂带的形态和伸展、两侧地块的对比、晚侏罗世-早白垩世的位移时间以及向北突出的北方苏北地块的左旋断裂成因。
The Tan-Lu fault zone, with hundreds of km of sinistral displacenent, is one of the largest continental strike-slip faults in the world. Four tectonic models recently proposed for the fault zone are reviewed in this paper: (1) intracontinental transcurrent fault, (2) suture line, (3) intracontinental transform fault, (4) and collision-related indentation. We propose that the Tan-Lu fault zone is a major transcurrent fault developed on the inner, continental side of the northwestern circum-Pacific margin. This conclusion is based on the shape and extension of the fault zone, correlation of blocks on either side of the zone, Late Jurassic to Early Cretaceous displacement time, and the sinistral fault origin of the northward-projecting Northern Jiangsu Massif.
