Formation conditions and geological structure of the Yenisei-Khatanga regional through

Abstract

A comprehensive analysis of geophysical data was carried out and a model of the deep structure of the Yenisei–Khatanga regional trough was constructed. A distinct platform appearance of the Neoproterozoic-Paleozoic sediments, the synchronous occurrence of ancient and Mesozoic sedimentary complexes in the axial most submerged part of the Yenisei–Khatanga linear depression. A wide territorial distribution of trap magmatism was revealed, which is not localized in the linear structure of the trough. It is concluded that the formation of the Yenisei-Khatanga regional trough is not associated with the Late Permian–Early Triassic rifting.
