Magmatism and metallogeny of the transverse structures of the North Urals
The article contains summarized results of the study of Late Paleozoic-Mesozoic magmatic complexes of the North Urals; there are three age levels of the plume-type intraplate magmatism: Permian-Triassic alkaline-acid (Torasoveysky, Levdievsky, Pon'insky complexes), Triassic-Jurassic trappean (M...

The article contains summarized results of the study of Late Paleozoic-Mesozoic magmatic complexes of the North Urals; there are three age levels of the plume-type intraplate magmatism: Permian-Triassic alkaline-acid (Torasoveysky, Levdievsky, Pon'insky complexes), Triassic-Jurassic trappean (Musyursky, Yatyinsky complexes), and Jurassic-Cretaceous alkaline-basite (Yalyayakhinsky, Marunsky, and Osoveisky complexes). The author shows their confinement to transverse disjunctive structures discordant to the general submeridional structure of the folded system. For the first time the author provides results of studying the isotope age of magmatites and describes their geochemical and metallogenic specializations. Thus, the Late Permian-Early Triassic stage is characterized by the manifestation of alkaline-acidic magmatism and associated mineralization of rare metal-albitite (Ta-Nb-Th-U) with gold and platinoids (Taykeusky, Longotsky deposits), quartz-fluorite and carbonatefluorite (Amderminsky deposit), and gold-copper-molybdenum-porphyry (Levdievsky manifestation) formations.
