Реферат:	eng: The first data of U-Pb isotopic study (LA-ICP-MS method) of zircon from tonalite-granodiorite forming a dominant part of the "trondhjemite" intrusive massif at the giant Tyrnyauz W-Mo deposit (North Caucasus) is presented. The concordant zircon isotopic U-Pb age obtained (302 +/- 4 Ma) indicates a Late Paleozoic (Late Carboniferous-Early Permian) age of crystallization of these rocks. This is consistent with the Late Paleozoic epoch of W-bearing magmatism and related W mineralization in the North Caucasus (Peredovoi Ridge) and allows the possibility of the Late Paleozoic age of the large bodies of altered skarn with W mineralization at the Tyrnyauz deposit.
