///In this paper, LA-ICP-MS U-Pb dating was carried out for zircons from granitic gneiss inclusions (xenoliths) in oft-com:office:smarttags" />Wugong Mountain area, central Qiangtang. The results show that granitic gneiss inclusions were formed in Late Triassic (209.1±2.8 Ma). This age is consistent with the existing research results of the convergence events of Gondwana and Eurasia in central Qiangtang, so the granitic gneiss inclusions are material records of the convergence events of Gondwana and Eurasia. All the results obtained by the authors can provide fresh evidence for the study of the properties of Qiangtang basement and the age of the convergence events of Gondwana and Eurasia.oft-com:office:office" />
