Figure 3. Distribution of the ages of rocks and their protoliths in the Vodlozero domain through the section: western accretionary zone-central part of the domain ("sialic core")-northern zone. 1 - gneisses, acid and intermediate volcanites; 2 - granites; 3 - tonalite-trondhjemite-granite series rocks; 4 - subalkaline series; 5 - gabbro and diorite; 6 -isochron age obtained by the Sm-Nd method from basalts and komatiites, with interval at the point showing analytical error; 7 - oldest zircon ages obtained on SHRIMP; 8 - whole rock Pb-Pb age from andesite. Vertical lines connect ages obtained from the same sample or massif. The age of the shaded area corresponds to the first phase of formation of the structure (marginal zones and sialic core).
