Norilsk-Talnakh nickel deposits
The nickel deposits of Norilsk-Talnakh are the largest nickel-copper-palladium deposits in the world. The deposit was formed 250 million years ago during the eruption of the Siberian Traps igneous province (STIP). The STIP erupted over one million cubic kilometers of lava, a large portion of it through a series of flat-lying lava conduits lying below Norilsk and the Talnakh Mountains.
The ore was formed when the erupting magma became saturated in sulfur, forming globules of pentlandite, chalcopyrite, and other sulfides. These sulfides were then "washed" by the continuing torrent of erupting magma, and upgraded their tenor with nickel, copper, platinum, and palladium.
