摘　　要：印支期以来,下扬子坳陷带古生代盆地受到了层滑构造的改造,经历了初始期、形成期和发展期。每期构造在平面上表现出明显的分带性,在剖面上由于受统一的区域性拆离面控制,古生代盆地可划分为下古生界构造系统和上古生界构造系统,两套构造系统具有不同的构造特征及油气生储盖条件。The Paleozoic basins in the Lower Yangtze Depression, which involved in initial (In-dosinian Epoch), forming (Early Yanshanian Epoch) and developing (Middle and Late Yanshanian) stages, have been remoulded by slip-sheet structures. The structures of each stage can be clearly zoned on plane. The Paleozoic basins can be divided into the Lower Paleozoic Era and the Upper Paleozoic Era structure systems as these structures were con-troled by the regional gliding-detachment surfaces, and these 2 systems have different structrual characteristics and production, reservoir and cover conditions for petroleum.
