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 gumbeites in the form of two facies varieties: carbonate-sericite-muscovite-orthoclase and quartz-carbonate-barite-adular varieties. Results of isotope studies (U-Pb, Rb-Sr, Re-Os, ⁴⁰Ar/³⁶Ar, ³He/⁴He, ²⁰Ne) of the aforementioned metasomatites and ore mineralization are discussed in the paper.

Ryabinovoe 斑岩型铜金矿床（南雅库特）：地质、岩壁蚀变、惰性气体同位素系统学和成矿过程的同位素定年

摘要在 Ryabinovoe 斑岩型铜金矿床区域，矿石成矿作用仅限于多期变质岩场，这些变质岩场分两个阶段形成。在第一阶段，即成矿前阶段，形成了高温钾钠变质岩（黑云母长石）；在第二阶段，形成了中低温壁岩胶粒岩，有碳酸盐-绢云母-绿泥石-正长岩和石英-碳酸盐-长石-金刚石两种面貌。文中讨论了对上述变质岩和矿石成矿作用的同位素研究结果（U-Pb、Rb-Sr、Re-Os、40Ar/36Ar、3He/4He、20Ne）。

期刊介绍： Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
