Two major types of Late Archean (2,74–2,7 Ga) intrusions cross-cut the greenstone rocks of the Ondozero-Segozero prospect, Karelia. They belong to two series moderately alkaline (sanukitoid) and calc-alkaline: 1 – differentiated (pyroxenites to syenites) and 2 – porphyraceous granitic complexes. Their structure, petro-geochemical characteristics and mineralization, responsible for the metallogeny of the territory: 1 – P-Ti-REE (with Pt), 2 – Cu-Pb-Zn-Mo (with Bi, Ag, Au), are discussed.
Keywords: moderately alkaline differentiated and granitic massifs, geochemistry, metallogeny, Archean, Ondozero-Segozero prospect, Karelia.
