Abstract: 8 rock samples were collected from the Fenghuangshan basement uplift zone of the northern Dabashan tectonic beltApatite fission track(AFT)dating were carried out and their timetemperature thermal modelings were performedThe results show the uplifting history can be divided into two stages since Early Cretaceous：late Early Cretaceous slow uplifting(135±5～95±5 Ma)，Late Cretaceous rapid uplifting(95±5～65±5 Ma).The biotite 40Ar/39Ar plateau age from mylonite in the Dabashan ductile shearing zone documents there was a rapid uplifting in the age of 165.7±1.9 Ma～161.2 Ma，it was related to intensive intracontinental orogenesis of the MtsDabashanThe late Early Cretaceous slow uplifting represented a period of relative stability after Late Jurassic intracontinental orogenesisThe Late Cretaceous rapid uplifting was concomitant with postorogenic extension and collapse of the Dabashan tectonic belt，featured by the development of rifted basins along the Qinling orogenic beltThis Late Mesozoic uplifting history of Fenghuangshan basement uplift can be compared with those of the adjacent basement uplift zones such as the Huangling and Hannan terrains，but differs significantly from the Wudang terrain of southern Qinling，indicating an unhomogeneous uplifting process of the Qinling orogenic belt in Late Mesozoic periodOne rock sample was collected from the foreland structural zone，its timetemperature thermal modeling result shows a similar uplifting history between the Fenghuangshan basement uplift zone and the foreland structural zone since Early Cretaceous.
