dc.description.abstract A comparative analysis was made between the traps of the Olenek uplift and the northeastern Tunguska syneclise, which showed that they differ in terms of petrography and petroand geochemistry. Their indicator pair ratios of incompatible elements (Zr/Nb, Nb/Th, Nb/Y, Zr/Y) form, in diagrams, two isolated fields, which suggests different sources. It is concluded that traps of the Tunguska syneclise and the Olenek uplift were associated with independent plume-magmatic events separated in time. Responsible for the formation of the Olenek uplift traps was the Olenek plume which caused the origination of the Olenek trap syneclise at the Permian Triassic boundary.
