Zircon Upb Dating And Geochemistry Of The Linong Granitoid And Its Relationship To Cu Mineralization In The Yangla Copper Deposit, Yunnan, China
RESOURCE GEOLOGY(2013)
Abstract
The Yangla copper deposit (Cu reserves: 1.2Mt) in the JinshajiangLancangjiangNujiang region in China is spatially associated with the Linong granitoid. Zircon UPb dating shows the granitoid formed at 234.1 +/- 1.2 to 235.6 +/- 1.2Ma, and the KT2 ore body of the deposit yields a molybdenite ReOs model age of 230.9 +/- 3.2Ma. 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.
