    Chemical and isotopic compositions of rocks, ores, and hydrothermal minerals from the Rainbow and Logachev-2 hydrothermal fields
    PANGAEA
    In:  Supplement to: Lein, Alla Yu; Ul'yanova, Nina V; Ul'yanov, Alexander A; Cherkashov, Georgy A; Stepanova, Tamara V (2001): Mineralogy and geochemistry of sulfide ores in ocean-floor hydrothermal fields associated with serpentinite protrusions.

    Description: The aim of this paper is to analyze and compare mineralogy and geochemistry of copper-zinc sulfide ores from the Logachev-2 and Rainbow hydrothermal fields of the Mid-Atlantic Ridge (MAR) confined to serpentinite protrusions. It was found that Zn(Fe) and Cu, Fe(Zn) sulfides had been deposited in black smokers pipes almost simultaneously from intermittently flowing, nonequilibrium H2S-low solutions of different temperatures. Pb isotope composition confirmed that the deep oceanic crust had been a source of lead. The ores from the Rainbow field are 20-fold higher in Co than ores restricted to basalts and show a high ratio of Co/Ni=46. The ores from the Rainbow field are enriched in 34S isotope (aver. d34S=10 per mil) because of constant flow of cold sea water into the subsurface zone of the hydrothermal system. Ores from the Logachev-2 field are 8 times higher in gold compared to other MAR regions. Sulfide ores from the Rainbow and Logachev-2 fields have no analogues among MAR ore occurrences in terms of enrichment in valuable components (Zn, Cd, Co, and Au).

    Chemical and isotopic compositions of hydrothermal manifestations and minerals from the Broken Spur hydrothermal field
    PANGAEA
    In:  Supplement to: Bogdanov, Yury A; Lein, Alla Yu; Maslennikov, Valery V; Li, Syaoli; Ul'yanov, Alexander A (2008): Mineralogical and geochemical features of sulfide ores from the Broken Spur hydrothermal vent field. Okeanologiya, 48(5), 734-756, https://doi.org/10.1134/S000143700805007X

    Description: A representative collection of hydrothermal manifestations was sampled practically from all hydrothermal mounds of the Broken Spur hydrothermal vent field with use of the Mir manned submersibles during three cruises of R/V Akademik Mstislav Keldysh. Mineral associations characteristic for different morphological types of sulfide ores from hydrothermal pipes, plates, and diffusers are assessed. Particular attention is paid to distribution of minor elements and their distribution patterns determined by mineralogical zonation. Measured isotopic composition of sulfur in sulfide minerals varies from 0.4 to 5.2 per mil that indicates their similarity with ores from the Snake Pit vent field and is related to dilution of hot ore-bearing solutions by seawater and reduction of water sulfate ions to H2S with heavy isotopic composition.

    Mineral and chemical compositions of hydrothermal ores and sediments from the Menez Gwen Hydrothermal Field, Mid-Atlantic Ridge
    PANGAEA

    Description: Mineralogy and geochemistry of sulfide-bearing rocks and ores discovered within the Menez Gwen Hydrothermal Field are studied. Samples were taken during Cruise 49 of R/V Akademik Mstislav Keldysh of the p.p. Shirshov Institute of Oceanology. Mineral composition of rocks and ores were studied by traditional methods of optical microscopy, scanning electron microscopy (CAMSCAN), and microprobe analysis (EPMA SX-50). Contents of trace elements were determined by laser ablation inductively coupled plasma - mass spectrometry (LA-ICP-MS). Zn-Cu ore comprises zonal sulfide chimney intergrowths. Numerous Se-rich copper ore fragments occur in volcanomictic layered gritstones and/or barite slabs. Mineral composition, zonality and association of trace elements in ore are typical of black smokers formed at the basalt base near the Azores Triple Junction in the MAR. Obtained results make it possible to reconstruct formation history of the Menez Gwen Hydrothermal Field into the high-temperature (Cu-Se association in ore clasts), medium-temperature (Zn-Cu-As association in ore), and recent (Ba-SiO2 association) stages.
