The Geology, Mineral Associations, and Composition of Native Gold in the Mineral Deposits of the Taimyr–Severnaya Zemlya Orogen
The variety of sizes and morphology of grains and chemical composition of native Au, and the diversity of mineral productive associations in the new ore occurrences of the Western and Central Taimyr (the Minina–Bolshevik miogeocline and the Shrenk–Faddeevskaya accretionary mineragenic zones) indicate the complex multicomponent composition of ore-forming systems and different physicochemical conditions of the formation of gold ore mineralization. The native Au characteristics and specific features of the geological structure of the objects point to the significant gold ore potential of the Central Sector of the Russian Arctic.
