Parameters for the Formation of the Dobroe Gold Deposit (Yenisei Ridge, Russia): Evidence from Fluid Inclusions and S–C Isotopes
نویسندگان
چکیده
The Dobroe deposit with 10 t gold reserves is one of the mines located within Yenisei Ridge Orogenic Belt. ore-forming conditions orogenic deposits are have recently been widely discussed. A comprehensive study fluid inclusions revealed that was formed by water–carbon dioxide and carbon dioxide–hydrocarbon fluids a temperature range 180 to 360 °C, pressure 0.8 1.3 kbar, salinity 1.5 15.0 wt.% (NaCl-equiv.). Gas chromatography–mass spectrometry showed consisted H2O, CO2, hydrocarbons, nitrogenated, sulfonated, chlorinated compounds. distribution patterns δ13C in (−11.3‰–−3.6‰) δ34S sulfides (1.9‰–17‰) indicate crustal source for ore-bearing fluids.
