Vendian foreland basin of the Siberian cratonic margin: Paleopangean accretionary phases [PDF]

open access: yesRussian Journal of Earth Sciences, 2002
Vendian, chiefly clastic sedimentation on the southwest of the Siberian craton is discussed under the tenet of a foreland basin that came into being in the Vendian epoch at the margin of the Siberian continent (craton) due to its collision with island arcs and microcontinents.

Geochronology of sillimanite-cordierite gneiss Atamanovo series of the South Yenisei Ridge (Russia)

open access: yesЛитосфера, 2017
The paper provides justification of Paleo Archaean age (3221 ± 15 Ma) of the granulite plutonic metamorphism that formed the Kan metamorphic complex of the Archaean crust in the Angara-Kan block of the Siberian craton. The age was defined on the basis of

THE SOUTHERN FRAGMENT OF THE SIBERIAN CRATON: “LANDSCAPE” HISTORY OVER TWO BILLION YEARS

open access: yesГеодинамика и тектонофизика, 2015
In the state-of-the-art geology, concepts of evolution of interrelated geodynamic and biotic events throughout the history of the Earth have been developed (Fig. 1). Research results on sediments, bio-stratigraphy and geodynamics of the southern fragment

Noril'sk/Siberian plateau basalts and Bahama hot spot: Impact triggered? [PDF]

open access: yes
Twenty-eight years after one of us argued that Sudbury was an astrobleme, this interpretation has only recently attained wide acceptance; not so for the view that the Sudbury Cu/Ni sulfide ores are cosmogenic.

New insights from low-temperature thermochronology into the tectonic and geomorphologic evolution of the south-eastern Brazilian highlands and passive margin [PDF]

open access: yes, 2019
The South Atlantic passive margin along the south-eastern Brazilian highlands exhibits a complex landscape, including a northern inselberg area and a southern elevated plateau, separated by the Doce River valley.

High Water Contents in the Siberian Cratonic Mantle: An FTIR Study of Udachnaya Peridotite Xenoliths [PDF]

open access: yes
Water is believed to be a key factor controlling the long-term stability of cratonic lithosphere, but mechanisms responsible for the water content distribution in the mantle remain poorly constrained.
