| 摘 要： | 北祁连盆地群位于青藏高原北部，长期处于欧亚大陆的边缘活动带，对构造运动有着敏感的反应，各次构造运动在该区都有表现。现今北祁连盆地群经历多次构造运动的改造，先后经历了早古生代大陆裂谷阶段、晚古生代稳定陆内沉积盆地阶段、中生代的板内变形阶段和伸展断陷阶段、新生代挤压变形与前陆盆地发育阶段，是各个时期盆地叠合的产物。

| Abstract: | The north Qilian basins in the north of the Qinghai-Tibet Plateau lies in the Eurasia continental marginal mobile belt. They are superimposition of multiple phase basins undergoing multiple tectogenesis from the Early Paleozoic continental rifting, through the Late Paleozoic stable intracontinental sedimentary basin and the Mesozoic intraplate deformation and faulting, to the Cenozoic compression deformation and foreland basin. |
