Zircon geochemistry of Edong granitoids in the Middle-Lower Yangtze Metallogenic Belt (Eastern China): Constraints on W-Cu-Fe skarn mineralization

It has long been established that skarn deposits of different metals are associated with intrusions of different compositions. Intermediate-felsic granitoids in the Edong district of the Middle-Lower Yangtze Metallogenic Belt host skarn deposits with varying W-Cu-Fe proportions, yet previous whole-rock geochemical studies could not distinguish between the magmatic suites that formed the different skarn deposits. In this study, LA-ICP-MS zircon...
