N2 - © 2014, Pleiades Publishing, Ltd. Primary data on material composition of epidote-garnet plagiogneisses from the crystalline basement of the Yangiyugan area (the northwestern part of West Siberia) are presented. It is found that plagiogneisses were formed over the substrate of leucocratic plagiogranites (trondhjemites) under the conditions of the amphibolites facies of metamorphism. The SHRIMP II U-Pb-dating of zircons showed that the igneous intrusion of plagiogranites proceeded during the Late Vendian (566 ± 3 Ma). Their metamorphism with the formation of plagiogneisses took place in the Early Ordovician (486 ± 4 Ma). The shows of powerful fluid-metasomatic processes of the transformation of rocks during the Carboniferous time are revealed.
