摘要：
Key factors for the formation of world-class magmatic Ni-Cu deposits include sulfide saturation in magma, large magma/sulfide ratio and accumulation of sufficient quantity of immiscible sulfide liquid in limited localities. Results from two well-known Ni-Cu deposits in the world, the Talnakh deposits in Siberia, Russia and the Voisey's Bay Deposit in Labrador, Canada, indicate that a dynamic magma conduit in the upper crust is an ideal environment in which these factors can prevail.
