摘要
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.
