THE PHENOMENON OF RAPID ACCUMULATION OF SEDIMENTS BELONGING TO THE UDOKAN GROUP AND THE FORMATION OF THE UNIQUE UDOKAN COPPER DEPOSIT (ALDAN SHIELD, SIBERIAN CRATON)

open access: yesГеодинамика и тектонофизика, 2020
We analyzed new geological and geochronological data on sedimentation and metamorphism in the junction area of the Aldan and Stanovoy Superterranes comprising the southern flank of the Siberian craton.

Palaeozoic orogeneses around the Siberian craton: Structure and evolution of the Patom belt and foredeep

open access: yes, 2009
International audienceThis paper sheds light on the evolution of the Patom belt. This mountain range draws an arc along the southeastern edge of the Siberian craton.

Mantle heterogeneity during the formation of the North Atlantic Igneous Province: Constraints from trace element and Sr-Nd-Os-O isotope systematics of Baffin Island picrites [PDF]

open access: yes, 2004
Sr-Nd-Os-O isotope and major and trace element data from ~62 Ma picrites from Baffin Island constrain the composition of mantle sources sampled at the inception of North Atlantic Igneous Province (NAIP) magmatism.

EARLY STAGE OF THE CENTRAL ASIAN OROGENIC BELT BUILDING: EVIDENCES FROM THE SOUTHERN SIBERIAN CRATON

open access: yesГеодинамика и тектонофизика, 2017
The origin of the Central-Asian Orogenic Belt (CAOB), especially of its northern segment nearby the southern margin of the Siberian craton (SC) is directly related to development and closure of the Paleo-Asian Ocean (PAO).

Eclogite induced deformation of the siberian craton

open access: yes, 2020
The deformation of the cratons, whose roots are approximately 250 km deep is very difficult. The removal of the mantle lithosphere, which is one of the proposed mechanisms for the deformation of the craton that is stable for long periods, is carried out by many different processes. Deformation of the craton as a result of a gravitational instability is

Tectonic Evolution and Structural Control of Dike-Hosted Orogenic Gold Deposits in the Yana–Kolyma Collision Orogen (Eastern Siberia): Insights from the Eastern Margin of the Siberian Craton

open access: yesGeosciences
The Yana–Kolyma collision orogen, Eastern Siberia, is one of world-class gold economic belts, where large gold deposits are localized, mainly in the Upper Paleozoic and Lower Mesozoic clastic rocks.

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
