摘要: 苏北盆地位于苏鲁造山带南侧、下扬子地台的东北部，盆地所处的特殊构造位置使其演化历史颇为复杂。总结了近年来苏北盆地构造演化研究方面的进展，如盆地基底、深部构造、形成机制、盆地与下扬子区构造演化之间的关系等研究的进展。对近年来获得的新认识进行分析和归纳，提出了今后苏北盆地构造演化研究中一些值得关注的问题，如盆地基底构造与浅部构造之间的关系、苏鲁造山带与盆地构造演化的联系、郯庐断裂对盆地形成的影响、盆地形成的动力学机制等。Abstract: The Subei basin is located in the northeastern part of the Yangtze platform, at the southern side of the Sulu orogen. This special tectonic location makes its evolution very complex. This review focuses on the recent progress in the study of the tectonic evolution of the Subei basin, especially on the basement, deep structure and formation mechanism of the basin and its relationship with the lower Yangtze region. This paper presents some problems to which attention should be paid in the future study of the tectonic evolution of the Subei basin through an analysis and summing-up of new geological data obtained in this area. They include the relation between the basement structure and shallow structure of the basin, relation between the Sulu orogen and the tectonic evolution of the Subei basin, influence of the Tanlu fault on the basin formation and kinematic mechanism of the formation of the Subei basin.
