New data on availability of volcanites in the boundaries of svecofennian part of Ladoga region allow to refine the svecofennian terrain geodynamics and evaluate the time of accumulation of the early-Proterozoic deposits in this region. The results of the petro- and geochemical research of metavolcanites show that this rock can be related to the lime-alkaline series of volcanites. Age is determined by U-Pb isotope method for zircon and monazite. The diagrams of Ti/Zr and Th/Yb-Nb/Yb ratios show that the rocks studied fall within the field of volcanites of the island arcs like volcanites of Finland.
