The large gold-telluride Svetlinsk deposit (~135 t Au) is considered to be a nontraditional one in the Urals and its origin is debated. A specific feature of the deposit is the abundance of various tellurides, such as tellurides of Fe, Ni, Pb, Sb, Bi, Ag, and Au. The new data of microthermometry, Raman spectroscopy, LA-ICP-MS, and crush-leach analysis (gas and ion chromatography, ICP-MS) for fluid inclusions as well as O-isotope data for quartz were obtained for the construction of PTX parameters of ore-formation and fluid sources in the deposit. Mineralisation was formed at a wide range of temperature and pressure (200–400 °C, 1–4 kbar) and from contrasting fluids with multiple sources. At the early stages, the magmatic fluid evolved during its ascent and phase separation and the fluid derived from the host rock decarbonation and dehydration were involved in the hydrothermal system. In addition, mantle-derived fluid might be involved in the ore-forming process during gold-telluride precipitation as well as heated meteoric waters during the late stages. Early fluids were rich in H2S, S0, and CH4, while the Au-Te mineralisation was formed from N2-rich fluid.

Abstract Intrusion-related Au-Bi deposits of North-East Russia are related to Late Mesozoic orogenic S- and I-type granites of ilmenite series. The studied deposits differ in their position relatively to the plutons, alteration, ore body morphology and sulphide content in ores. Based on mineral composition of ores, studied deposits are divided into bismuth-sulphotelluride-quartz, bismuth-arsenide-sulpharsenide and bismuth-siderite-polysulphide types. Bismuth-sulphotelluride-quartz deposits (Levo...

Nearly pure N2 fluid inclusions (Th (L) = −151~−168 °C; Th (V) = ~150.3 °C) were identified in W-mineralized quartz veins from the Yangjingou scheelite deposit, in the eastern Yanbian area, NE China. Other fluid inclusion populations include N2-CO2, NaCl-H2O ± N2 and CO2 ± N2-NaCl-H2O, but no hydrocarbons were detected. The host rocks are part of the Wudaogou Group metamorphic series, which mainly consist of Ca-rich mica schist. Subhedral sulfide minerals occur in early disseminated W-mineralize...

Abstract The Berezovsk gold deposit in the Middle Urals has been mined for 270 years. Its endowment (past production and gold reserves) is estimated to be 490 t of gold. The deposit is located in the greenschist metamorphosed Silurian volcanogenic-sedimentary rocks intruded by granitoid dykes to the north-east of Late Carboniferous Shartash granite massif. Mineralisation is represented by sulphide-quartz veins in the granitoid dykes (“ladder” veins) and in the host rocks (“krassyk” veins) formed...

Abstract The Urals VMS province comprises a broad spectrum of variably metamorphosed deposits, from unmetamorphosed to those without any primary ore textures, which are the results of high-grade metamorphic processes. Contact metamorphism near large granite and granodiorite plutons caused the most significant changes of ores, with coarse-grained to pegmatoidal ores with magnetite closest to its contact with the intrusion, followed by pyrrhotite-enriched copper ores, and more distal zinc (± Pb ± ...

Abstract The Urals is a complex fold belt, which underwent long geological evolution. The formation of most gold deposits in the Urals is related to the collision stage. In this paper, we review some relatively small listvenite-related gold deposits, which are confined to the large Main Uralian fault zone and some smaller faults within the Magnitogorsk zone. The Mechnikovskoe, Altyn-Tash, and Ganeevskoe deposits are studied in detail in this contribution. They comprise the ore clusters along wit...

Abstract This study of metallogeny of the Urals is strongly tied up with a stage-by-stage geodynamic analysis of the orogen. The analysis includes a revised understanding of geodynamic development of the Timanides (development of a deep sedimentary basin since the Mesoproterozoic, ocean formation and subduction in the Neoproterozoic and collision in the Late Ediacaran). For the Uralides, a new interpretation includes relationships between Tagil and Magnitogorsk arcs, arc–continent collision in t...

Many types of hydrothermal ore deposits form at overpressured conditions during high fluid flux through fault zones in the continental seismogenic regime. These include many orogenic gold deposits, some types of Fe oxide Cu-Au systems, and a variety of intrusion-related deposits, including some high-sulfidation epithermal systems. The internal structures of these deposits indicate formation while faults were active, in a regime involving episodic slip. Partial to complete sealing of fault zones ...

The Logrosan Sn–(W) ore deposits in the metallogenic Sn–W province of the European Variscan Belt consist of endo- and exogranitic greisen-type and quartz–cassiterite veins associated with a S-type granite. Mineral characterization, fluid inclusion study, isotope geochemistry and Ar–Ar geochronology have been combined in order to reconstruct the conditions for Sn–(W) mineralization. The endo- and exogranitic mineralization must have been developed in a relatively long-lived system (~ 308–303 Ma),...

Structural geological studies were conducted between 2009 and 2014 in the quarry of Svetlinskoe gold deposit (South Urals). Svetlinskoe gold deposit is located in zone of the large west dipping thrust. Three types of quartz veins accompanying gold-bearing pyrite-quartz-biotite metasomatites are identified: 1) the largest steep deep veins of sub-meridional orientation; 2) the most numerous steeply dipping sub-latitudinal veins; 3) sub meridional low density small-size veins shallow dipping to the...
