Abstract

The rock assemblages of the Vedlozero-Segozero greenstone belt (Central Karelia) were used as reference pattern for the study of Archean crustforming processes of the Karelian Craton. This paper presents geochemical and U-Pb (SHRIMP II) zircon dating data for the mafic and andesite rocks. The results obtained by using the approach, based on the analysis of the volcanic rocks, combined with intrusive and sedimentary rocks, maintain the model of the initial stage of the assembling of the Karelian Craton.

Keywords: Magmatic systems; Archean; Karelia craton; Komatiite; Adakite
