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.

Subject of study. The article presents the results of study of trace elements (TEs) in sulfides of the main ore body (borehole 1T) and the northwestern ore body (borehole 200) of the Dergamysh cobalt-bearing massive sulfide deposit hosted in serpentinites (South Urals). Materials and methods. The chalcopyrite-pyrite-marcasite sandstones of the main ore body and pyrite-chalcopyrite-pyrrhotite “gravelites” of its northwestern satellite were studied with laser ablation with inductively coupled plasma. Results. The TE contents, distribution and mode of occurrence differ in sulfides of the main ore body and its northwestern satellite. In ores of the main ore body, most TEs (Ag, Sn, Mn, As, Co, Ni, Te, Pb, Au) accumulate in pyrite-1, pyrite-marcasite aggregates concentrate Tl and Bi, marcasite is a host to Mo and Sb, and chalcopyrite contains Zn, Se and Cd. Pyrite-2 is depleted in TEs relative to other sulfides. In sulfides of the northwestern satellite, most TEs are related to chalcopyrite (Bi, Te, Zn, Cd, Se, Pb, Au, Tl, Ni, Co). Tin accumulates in cubanite, As and Ni are hosted in pyrite-4, Ag, Mn and Mo are concentrated in pyrrhotite, Sb is typical of pyrite-3, and Co accumulates in pyrite-2. Conclusions. Based on the correlation analysis, it is shown that sulfides of the main ore body and its northwestern satellite are characterized by different mode of TE occurrences. The differences are explained by two main reasons: 1) “mafic” and “ultramafic” metal sources for sulfides of the main ore body and its northwestern satellite, respectively, and 2) different degree of diagenetic alteration of sulfides.
