| Isotope Geochronology Study for “POG Type” Granite in Bayan Har Terrain |
| Bayan Har terrain lies in the northern part of the Tibet plateau, and between the Kunlun terrain and Qiantang terrain. there are many granite outcrops in the eastern part of Bayanhar terrain. The 39 Ar- 40 Ar age of biotite and the 207 Pb/ 206 Pb age of zircon indicate the granite body formed at 220～212 Ma. After that, the granite had undergone two times metamorphism and deformation at 148 Ma and 110Ma。 |
