| SHRIMP Dating of Baimaxueshan and Ludian Granitoid Batholiths, Northwestern Yunnan Province, and Its Geological Implications |
| SHRIMP U-Pb ages are reported for the Baimaxueshan and the Ludian granitoid batholiths in northwestern Yunnan Province. The Baimaxueshan granodiorite intruded at 239 ± 6 Ma, whereas the Ludian biotite monzonite granite, 214 ± 6 Ma. These data provide geochronological evidence for the collisional events of Jinshajiang area. |
