Thorough information on geological structure of the Ukrainian shield (USh) allows to verify opinions existing nowadays that plume and plate tectonic activities are possible only after conclusive formation of sublithospheric mantle 2,8—2,55 Ga and plume episodes of Precambrian occurred 2,75—2,7, 2,45...
