| Реферат: | eng: The Blagodatnoye deposit with 340 t gold reserves is one of the most productive mines in Russia. Modern methods of studying fluid inclusions were used to determine the properties of fluids that formed this deposit. A comprehensive study revealed that the Blagodatnoye gold deposit was formed between 120 and 350 & DEG;C and at 0.2-2.6 kbar, and from fluids with salinities ranging from 0.5 to 30 wt.% (NaCl-eq.). These fluids are: 1-water-carbon dioxide; 2-carbon dioxide-hydrocarbon; 3-highly saline aqueous. According to Raman spectroscopy and gas chromatography-mass spectrometry, ore-forming fluids contained H2O, CO2, hydrocarbons and oxygenated organic compounds, sulfonated, nitrogenated and halogenated compounds. Early oxidized water-carbon dioxide fluids formed barren associations of the deposit. Later reduced carbon dioxide-hydrocarbon fluids had a key role in the formation of gold-bearing quartz veins. The stable isotope data (delta S-34 = 0.8 to 21.3 & PTSTHOUSND;, delta C-13 = -2.8 to -20.9 & PTSTHOUSND;, He-3/He-4 = 0.14 & PLUSMN; 0.3 x 10(-6)) suggest the ore-forming fluids have a crustal source.
