The Yangla copper deposit, situated in the middle section of Jinshajiang joint belt between Zhongza-Zhongdian plate and Changdu-Simao plate, is a representative and giant copper deposit that has been discovered in Jinshajiang-Lancangjiang-Nujiang region in recent years. There are coupled relationship between Linong granodiorite and copper mineralization in the Yangla copper deposit.LA-ICP-MS zircon U-Pb dating has revealed that the ages of two samples from the Linong granodiorites are (234.1±1.2) Ma(MSWD=0.66) and (235.6±1.2) Ma(MSWD=0.66), respectively. Molybdenite Re-Os model age for the KT2 ore body in Linong ore block is (230.9±3.2) Ma. It is the significance for finding out genetic type of the Yangla copper deposit and prospecting.
