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 ar

The basalt-hosted Semenov-2 hydrothermal field on the Mid-Atlantic Ridge is host to a rather unique Cu-Zn– rich massive sulfide deposit, which is characterized by high Au (up to 188 ppm, average 61 ppm, median 45 ppm) and Ag (up to 1,878 ppm, avera

Seafloor massive sulfides from mid-ocean ridges: Exploring the causes of their geochemical variability with multivariate analysis
Autor: Irina Yu. Melekestseva, Luca Toffolo, Paolo Nimis, V. E. Bel’tenev, Gennady A. Tret'yakov
The neovolcanic zones of mid-ocean ridges are host to seawater-derived hydrothermal systems forming seafloor massive sulfide (SMS) deposits. These deposits have high concentrations of base metals and potentially economic enrichment of a wide range of

Cu–(Ni–Co–Au)-bearing massive sulfide deposits associated with mafic–ultramafic rocks of the Main Urals Fault, South Urals: Geological structures, ore textural and mineralogical features, comparison with modern analogs
Autor: I. Yu. Melekestseva, V. V. Zaykov, Svetlana G. Tessalina, Gennady A. Tret'yakov, Paolo Nimis
Publikováno v: Ore Geology Reviews. 52:18-36
Cu-rich massive sulfide deposits associated with mafic–ultramafic rocks in the southern portion of the Main Urals Fault (MUF) are characterized by variable enrichments in Ni (up to 0.45 wt.%), Co (up to 10 wt.%) and Au (up to 16 ppm in individual h

Seasonal and centennial cycles of carbonate mineralisation during the past 2500 years from varved sediment in Lake Shira, South Siberia
Autor: Gennady A. Tret'yakov, Andrey Darin, Denis Yu. Rogozin, Ivan Kalugin
Publikováno v: Quaternary International. :245-252
Shira Lake is a good representative object for detail weather–climate modeling due to its local hydroclimatic information and annually laminated bottom sediments. Carbonate biochemical mineralization in Shira Lake shows not only seasonal but also c

Autor: Ivan Kalugin, Andrey Darin, Gennady A. Tret'yakov, Ya. V. Rakshun, M. A. Maksimov
Publikováno v: Bulletin of the Russian Academy of Sciences: Physics. 77:185-187
The interannual and interseasonal variations in the trace element composition of annual layers in bottom sediments of Lake Shira (Khakassia) are studied by means of X-ray scanning microanalysis with synchrotron radiation on the VEPP-3 (Novosibirsk) a
