英文摘要: Abstract(#br)The Laji Shan and Daban Shan which are located along the southern and northern margins of the Xining Basin in the northeastern Qinghai–Tibetan Plateau, experienced important multi-stage exhumations during the Cenozoic. The apatite fission track (AFT) dating of 19 samples along four north–south sections in the Laji Shan and Daban Shan showed that the AFT ages of the Laji Shan from 88Ma to 12Ma and the ages of the Daban Shan are between 60 and 32Ma. All these AFT ages are significantly younger than their host rock formation or sediment deposition ages. Thermal modeling of the AFT data indicated that the Laji Shan had undergone important exhumation events in the Late Cretaceous, ca. 50–30Ma, and...
