Thermochronological Evidence for Multi-Phase Uplifting of the East Kunlun Mountains, Northern Tibetan Plateau
详细信息   
摘要

Multiple phases of Mesozoic and Cenozoic cooling and uplifting events are derived from fission track (FT) dating of zircons and apatites and thermal history modeling of apatite FT ages from several plutons in East Kunlun near Golmud City. Two phases of Mesozoic cooling histories revealed by zircon FT ages are phase I in Jurassic (194.1144.4 Ma)  and phase II in Early Cretaceous (115.7100.2 Ma). According to the age comparability of the end of thrusting in Cenozoic phase II and the beginning of the major sinistral strike-slipping of Kunlun Fault, it is inferred that there was a deformational transfer from compressing to shearing at 10.0 Ma.
