Crustal structure of the Siberian craton and the West Siberian basin: An appraisal of existing seismic data

Tectonophysics, 2013
AbstractWe present a digital model SibCrust of the crustal structure of the Siberian craton (SC) and the West Siberian basin (WSB), based on all seismic profiles published since 1960 and sampled with a nominal interval of 50km. Data quality is assessed and quantitatively assigned to each profile based on acquisition and interpretation method and ...

Age of the Siberian craton crust beneath the northern kimberlite fields: Insights to the craton evolution

Gondwana Research, 2016
Abstract Comprehensive studies of zircon xenocrysts from kimberlites of the Kuoika field (northeastern Siberian craton) and several kimberlite fields of the eastern Anabar shield, along with data compilation on the age of kimberlite-hosting terranes, reveal details of the evolution of the northern Siberian craton.

Density heterogeneity of the cratonic lithosphere: A case study of the Siberian Craton

Gondwana Research, 2015
Using free-board modeling, we examine a vertically-averaged mantle density beneath the Archean–Proterozoic Siberian Craton in the layer from the Moho down to base of the chemical boundary layer (CBL). Two models are tested: in Model 1 the base of the CBL coincides with the LAB, whereas in Model 2 the base of the CBL is at a 180 km depth.

The Siberian lithosphere traverse: mantle terranes and the assembly of the Siberian Craton

Tectonophysics, 1999
Abstract The kimberlite fields scattered across the NE part of the Siberian Craton have been used to map the subcontinental lithospheric mantle (SCLM), as it existed during Devonian to Late Jurassic time, along a 1000-km traverse NE–SW across the Archean Magan and Anabar provinces and into the Proterozoic Olenek Province.

Mantle sources of Permian-Triassic Siberian traps (West Siberian Plate and Siberian craton)

Russian Geology and Geophysics, 2008
Abstract We investigate the dynamics of multilevel subcontinental melting beneath a lithosphere of variable thickness as a model simulating generation of melts that produced flood basalt in the Siberian Trap province. The inferred sequence of volcanic events correlates with upper mantle decompression melting above hotspots and related ...

The Siberian Connection: A case for Precambrian separation of the North American and Siberian cratons

Geology, 1978
The hypothesis that the Cordilleran geosyncline originated as an Atlantic-type continental margin by the rifting of an older Precambrian continental mass and the opening of a new ocean basin leads to the question of where the counterpart of the North American Precambrian craton may be.

Paleomagnetism of the Ulkan trough (Southeastern Siberian Craton)

Russian Journal of Pacific Geology, 2013
The first results of the paleomagnetic study of one of the key Paleoproterozoic objects of the Aldan-Stanovoy Shield (the Ulkan trough) in the Bilyakchan-Ulkan volcanoplutonic belt are presented. The volcanosedimentary rocks of the Elgetei Formation and the granites of the Ulkan Complex were studied.

Antiquity of peridotitic diamonds from the Siberian craton

Earth and Planetary Science Letters, 1997
Abstract Diamonds erupted by kimberlites traversing ancient continental tectosphere [1] provide a window into the evolution of continents and their mantle keels. However, the vintage of this window; that is, the timing of crystallization of peridotitic mineral inclusion-bearing diamonds beneath different cratons, has proved controversial because of ...
