Abstract
We report the first U-Pb dates for allochthone hypersthene granites-kuzeevi tes-from the Angara-Kan protrusion of the Yenisei Range. The obtained age o f 1734 +/-4 Ma marks the termination of folding and metamorphism under the PT-conditions of granulite facies which determined the internal structure o f the Kan crystalline rocks.
