Abstract
This paper presents age data of the Elabuga zone rocks metamorphism and of the detrital zircon of the Elabuga zone paragneisses and their correlation with the age of Middle-Volga megablock rocks. The Elabuga zone rocks and the Middle-Volga megablock rocks have similar geochemical characteristics and degree of metamorphism. Difference is as follows: Paleoproterozoic metamorphism is occurred at the studied Elabuga zone rocks and such metamorphism age is not presented at the Middle-Volga megablock rocks. The study of U-Pb isotopic system in external zones in the Elabuga deformation zone zircon crystals suggests that rocks were underwent by metamorphism of two stages 1.99 and 1.95 Ga ago.
