The paper provides justification of Paleo Archaean age (3221 ± 15 Ma) of the granulite plutonic metamorphism that formed the Kan metamorphic complex of the Archaean crust in the Angara-Kan block of the Siberian craton. The age was defined on the bas

The late paleoarhean (3297±22 Ma) age of tonalite gneisses was at first identified on West-Azov block. They are characterized by a positive value of εNd(3300) = 0,3÷1,8, that they are juvenile source. With the new geochronological data, in the wes
