Metallogenic Mechanism of the Galinge Polymetallic Iron Skarn Deposit, Qiman Tagh Mountains, Qinghai Province

In the Qiman Tagh metallogenic belt, Fe, Zn, Pb, Cu and Au skarns and epithermal Cu and Mo deposits are spatially and temporally associated with Triassic granitoid rocks including granodiorite, monzogranite and syenogranite which are only occurred in the South Qiman Tagh Terrane as a result of completely different geotectonic setting between the SQT and NQT. The plutonic associations related to mineralization have various ages between middle-Triassic (237 Ma–226 Ma) and late-Triassic (226 Ma–204 Ma). The abundant volatile components evolved from magma are responsible for the significant transportation of metals. The initial oxygen fugacity of magma will affect the different mineralization types.
