摘要
In this paperascii-font-family: ’Times New Roman’">，the geological characteristics of the major granitic plutons in the area have been investigatedascii-font-family: ’Times New Roman’">，and their isotopic ages are systematically dated through the zircon LA-ICPMS U-Pb methodascii-font-family: ’Times New Roman’">．Combined with some known chronological data of the granitic plutons in this area from other workersascii-font-family: ’Times New Roman’">，this paper has constrained the intrusion and crystallization time framework of the granitic plutons in Jueluotage to be between 386Ma and 230Maascii-font-family: ’Times New Roman’">．The granitoid magmatic activity can be divided into four stages. Based on the post-collision theory and the results for the orogeny of Central Asia and northern Xinjiang, there display affinitive relationship between the granitoid magmatic activity and the tectonic evolution in tht study areaascii-font-family: ’Times New Roman’">．This paper further proposes a model for the evolution of granitoids in Jueluotage areaascii-font-family: ’Times New Roman’">．
