Keywords: Fennoscandian shield; Archaean; U-Pb age; geodynamic settings

An updated scheme of stratification of greenstone formations of the Kichanskaya structure is proposed. The ages (U-Pb according to zircon) of crystallization and metamorphism of volcanic rocks have been determined. The sequence of formation of the identified strata and the duration of geodynamic regimes have been established.
