Popis:	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 basis of zircon and was calculated as per207Pb/206Pb. Zircon was extracted from cordierite-sillimanite gneiss of the Atamanovo series. Gneiss contains zircons of the Meso-Archaean, Lower Paleo Proterozoic and Lower Proterozoic gneiss characterizing successive tectono-magmatic events reflected in paleometamorphite.
