Resumo
The ages values of the minerals that make up the ores of the Chudnoe deposit, established using isotope geochronology methods, do not allow us to correctly estimate the time of formation of Au-Pd mineralization due to the lack of reliable signs of their syngeneticity with gold. Based on linking isotope-geochronological data with the history of the geological development of the Subpolar Urals and the entire complex of endogenous and exogenous processes which determined the features of its geological structure and minerageny, the Early Paleozoic age of mineralization is substantiated. The similar age of the metarhyolites hosting the mineralization suggests not only a spatial, but also a paragenetic relations between ore mineralization and felsic volcanites. When studying the mineral composition and structural and textural features of ores, it is necessary to take into account the imposition of post-ore processes, especially the most powerful metamorphism manifested in the Subpolar Urals, the peak of which occurred in the Upper Paleozoic (~250 Ma).
