Geochemical and isotopic signatures of nonsubduction mechanisms of formation of the Neoarchean continental lithosphere of the Fennoscandian shield

  • A. B. Vrevskii


This study presents new data on the geochemical and Sm-Nd isotope compositions, as well as the U-Pb age and geodynamic nature, of the Neoarchean basalt-andesite-dacite (BAD) association from the Kolmozero-Voron’ya greenstone belt. As it was first demonstrated by the example of the Neoarchean greenstone belt, the formation of BAD associations within a single Neoarchean greenstone structure may be explained by the long-lasting evolution of separate mantle or crustal sources not related to subduction processes.
