Abstract
Abstract: In the territory of the Ryabinovoe porphyry copper-gold deposit, ore mineralization is confined to multi-stage metasomatism fields, which were formed in two stages. At the first, pre-ore stage, high-temperature potassium-sodium metasomatites (aegirine feldspathites) were formed, at the second stage, medium-low-temperature wallrock gumbeitesin the form of two facies varieties: carbonate-sericite-muscovite-orthoclaseand quartz-carbonate-barite-adularvarieties. Results of isotope studies (U-Pb, Rb-Sr, Re-Os, 40 Ar/36 Ar, 3 He/4 He, 20 Ne) of the aforementioned metasomatites and ore mineralization are discussed in the paper.
