A study of the ore facies of the massive sulfide ores from the Yubileynoe deposit (ore body № 2) has been shown. The sub-seafloor and seafloor hydrothermal, biogenic, clastic and seafloor hypergenic facies have been diagnosed in the studied ores, reflecting different formation conditions within the ore body № 2. The seafloor and sub-seafloor hydrothermal facies occur in the central part of the ore body, while clastic with seafloor hypergenic facies dominate at the flanks of the ore body. Rare minerals are native gold, minerals of Ag, Te, Bi and Pb widespread in seafloor hydrothermal and clastic ore facies. The ratio of the ore facies in the ore body № 2 shows the simiiar ore-forming processes within the Yubileynoe deposit and other massive sulfide deposits of the Urals.

LA-ICP-MS data on trace element zonation reflecting a local variation of physicochemical conditions of mineralization in black, grey and clear smokers from the Pacific and Atlantic oceans are used for comparison with the ancient chimneys of the Urals, Rudniy Altai, Pontides and Hokuroko massive sulfide deposits. Host rocks also influence on high-tech trace element assemblages in chalcopyrite: ultramafic (high Se, Sn, Co, Ni, Ag and Au) ! mafic (high Co, Se, Mo and low Bi, Au and Pb) ! bimodal mafic (high Te, Au, Ag, Bi, Pb, Co, moderate Se, and variable As and Sb) ! bimodal felsic (high As, Sb, Mo, Pb, moderate Bi, and low Co, Te and Se). In sphalerite of the same range, the contents of Bi, Ga, Pb, In, Ag, Au and Sb increase versus Fe, Se, Sn and Co. The variations in pyrite coincide with these changes. Diagenetic evolution of high-tech elements is recognized in sulfide nodules.
