Siberia has a prominent position in Russia, in terms of mineral resources and mineral production including copper, nickel, PGM's, uranium, molybdenum, tungsten, tin, manganese, gold, silver, lead, tantalum-niobium, rare earths, diamonds and many other mineral commodities. These resources are represented by a vast array of mineral systems and deposit styles in their respective terranes spanning the Precambrian and Phanerozoic geological history. These mineral systems include VHMS and SEDEX lead-zinc, orogenic gold, sediment- and shear-zone hosted to intrusive-related silver to silver-tin, alkaline gold to gold-uranium and uranium, porphyry copper and copper-molybdenum, epithermal gold, gold-silver, silver, gold-antimony, mercury, uranium-fluorite, various granite-related deposits (W, Mo, Sn, Be, Ta, Co-Ni, etc.) including those associated with peralkaline granites (Nb-Ta-Zr-REE), skarn iron, lead-zinc, gold, tungsten, carbonatite tantalum-niobium, niobium-REE and REE, magmatic copper-nickel-PGM sulfide, PGM and mafic intrusion-hosted iron-titanium-vanadium deposits, and diamondiferous kimberlites. Some deposits are large and superlarge including the well-known Noril'sk nickel-copper-PGM and Udokan copper deposits, the Sukhoi Log, Olympiada, Nezhdaninskoe, Kubaka, Kupol gold deposits, the Dukat and Prognoz silver deposits, and the Yakutian diamondiferous kimberlites. Apart from the above-mentioned giant deposits, several others are poorly known and/or unknown to western geoscience. The study of these mineral systems can significantly contribute to our further understanding of the metallogeny of cratons and orogenic belts, orogenic collages, and anorogenic settings. This provides additions to, and further development of, existing classifications and genetic models of mineral systems, allowing researchers to elucidate unknown or poorly studied mineral systems and styles found in Siberia, and to search for some other important styles that appear to be missing, although they are present in other regions with similar geological and tectonic settings.
