| The SHRIMP U-Pb Age of Matouwan Diopside Granite Porphyry in Yunnan Province |
| The SHRIMP technique was applied to determining U-Pb age of the Matouwan diopside granite porphyry in western Yunnan Province. The results show that the Matouwan diopside granite porphyry was intruded at 34 Ma,which should be Oligocene in time and belong to Himalayan period. The age indicates that the Ailaoshan-Jinshajiang deep fracture zone is controlled by the collision of the Indian plate with the Eurasian continental plate at about 40 Ma.The formation of Matouwan diopside granite porphyry must have had inherent connection with the collision of the two plates. |
