Abstract:The Yangla copper deposit (Cu reserves: 1.2 Mt) in the Jinshajiang–Lancangjiang–Nujiang region in China is spatially associated with the Linong granitoid. Zircon U–Pb dating shows the granitoid formed at 234.1 ± 1.2 to 235.6 ± 1.2 Ma, and the KT2 ore body of the deposit yields a molybdenite Re–Os model age of 230.9 ± 3.2 Ma. The ages of mineralization and crystallization of the granitoid are identical within the measurement uncertainties, suggesting the Yangla deposit is genitically related to the Indosinian Linong granitoid.
Keywords:Cu mineralization  geochemistry  granitoid  Yangla copper deposit  zircon U–  Pb dating
