Nature of zircon clastics in the Riphean and Vendian sandstones of the Southern Urals

open access: yesGeoresursy, 2019
New age dates of detrital zircons of terrigenous rocks augmented the possibilities of interpretation of their provenance. Unfortunately this interpretation is restricted by a formal comparison of age-and-composition characteristics of detrital crystals ...

Geodynamic control on the petroleum habitat of the Uralian Foreland

open access: yesGeoresursy
A comparative study of the Uralian Foreland in the Timan-Pechora and Volga Urals basins reveals considerable differences in structure and petroleum habitat. These differences were in large measure controlled by their geodynamic settings.

Plumes - a new word in Geology of the Urals

open access: yesЛитосфера, 2018
Subject. The ideas of plume tectonics became active and developing only several years later than the theory of plate tectonics. But in the Urals, the question of plume tectonics, contrary to plate tectonics, was not raised, with rare exceptions, until ...
