Abstract: The Vorontsovskoye gold-ore deposit (Northern Urals) generally corresponds to the Carlin-type. One of the deposit features is the presence of numerous dykes of mafic and middle chemical composition, of normal and increased alkalinity. Sm-Nd isotope studies for the first time confirmed the dykes formation age 340 ± 35 Ma. These data can be indicative of the post-collisional stage of magmatism in this area. The positive Nd values suggest a probable abyssal magmatic source of Nd.
