Age and isotope geochemistry of ore-hosting granodiorites of the Nyal’m-1 gold deposit (Kolmozero-Voron’ya greenstone belt, Kola Peninsula)

In spite of the long history of investigation of the GSB KV and numerous estimations of the isotope age of volcanoplutonic complexes and polymetamorphic processes of their transformation by different methods, the age of for mation of gold ore deposits is currently debated. This study was aimed at estimation of the age of the Nyalm 1 gold deposit spatially and genetically related to the granodiorite intrusion and Mg FeCa metasomatic rocks in them by modern local isotope geochemical methods.
