Physical-chemical conditions and composition of ore-building fluids of Russian oroganic gold deposits
The detailed research of fluid inclusions and stable isotopes in minerals of industrial ore veins large-scale orogenic gold deposits of different regions of Russia was carried out. The deposits under investigation are Berezovsk and Kochkarskoye (Ural), Olympiada (the Yenisei Ridge), Mayskoye (Chukot...
