Vendian magmatism of the Ufalei block (Central Urals megazone of the Middle Urals)

The first isotopic data on the age of the metagabbro-metatrondjemite complex are presented. For the first time identified in this composition (metagabbro, amphibolites and metatrondhjemite granofelses), the Kenchur complex composes small massifs in the central part of the Ufaley block, which is part of the Central Ural zone. The geochemical, mineralogical and isotopic data of the rocks of the Kenchur complex are considered. Based on these data, the contrasting composition and Early Vendian age of the complex, which was previously considered Late Riphean, was proven.
