Analysis of the total of data shows that sinistral strike-slip deformations were present not only in southern Siberia but also between the Siberian and European Platforms. Thus, the deformations of the Central Asian crust in the early Late Jurassic reflect the intraplate strike-slip motions coeval with the closure of the Mongol-Okhotsk Ocean and are governed by the clockwise rotation of the Siberian part of the Eurasian plate relative to its European part.
The geodynamic evolution of the folded framing and the western margin of the Siberian craton in the Neoproterozoic: The formation of the western margin of the Siberian craton in the Neoproterozoic is considered, with a focus on its transformation from a passive continental margin into an active one, accretion and collision processes, formation of island arcs and ophiolites, orogeny, and continent-marginal rifting. The evolution and correlation of sedimentary basins within fold-thrust belts of the Siberian Platform framing are considered.
New structural and kinematic data on the Yenisei fault zone are discussed. On the basis of paleomagnetic data obtained for the structures in the zone of junction of the Siberian Platform and the West Siberian Plate, new models are proposed for the location of the Siberian craton relative to other paleocontinents and microcontinents in the Neoproterzoic.
All these data provide a consistent evolution scheme for the western margin of the Siberian paleocontinent in the Neoproterozoic and constrain the position of the Siberian craton margin in Late Neoproterozoic pre-Vendian time.
New structural, petrological, chemical, isotope, and paleomagnetic data have provided clues to the Late Riphean-Paleozoic history of the Uda-Vitim island arc system UVIAS in the Transbaikalian sector of the Paleoasian ocean, as part of the Transbaikalian zone of Paleozoids.
The island arc system consists of three units corresponding to main evolution stages: The earliest stage produced the base of the system composed of Late Riphean ophiolite Ma, U-Pb and volcanic Ma, U-Pb and sedimentary rocks hemipelagic siliceous sediments and dolerite sills which represent the Barguzin-Vitim oceanic basin and the Kelyana island arc.
The main event of the second stage was the formation of the large UVIAS structure overkm2 which comprised the Transbaikalian oceanic basin, the forearc and backarc basins, and the volcanic arc itself, and consisted of many volcanic-tectonic units exceeding km 2 in area Eravna, Oldynda, Abaga, etc.

The rocks were studied in terms of their biostratigraphic and isotope age constraints, as well as major- and trace-element compositions, and were interpreted as products of weathering and tectonic-magmatic rework of the UVIAS units.
Yu The history of the Karagas Supergroup evolution in the Biryusa region: We summarize the results of paleomagnetic and sedimentological studies of the Neoproterozoic rhythmic terrigenous-carbonate rock unit in the Karagas Supergroup, which were carried out in the middle reaches of the Biryusa and Uda Rivers. The paleomagnetic data are presented along with a detailed description of the studied sections and the specific sedimentological characteristics of the studied deposits.
The new data refine the position of Late Precambrian paleomagnetic poles in Siberia and mark the paleogeographic and facies features of the rock unit formation. They also show that the rock unit was deposited much more rapidly than it was supposed earlier, in the environment of shallow-water sea basin on the margin of the Siberian continent. The origin and evolution of the Karagas sedimentary basin was governed by both global and regional tectonic factors. We suppose that the onset of the basin can be linked to a tectonic event, namely, the opening of ocean in southern Siberia during the break-up of Rodinia.
Regional tectonic processes controlled the position of the Karagas sedimentary basin and its evolution. International Association for Godwana Research. This paper presents paleomagnetic data for Late Mesozoic Middle Jurassic to end-Cretaceous rocks of the Siberian platform Verkhoyansk Trough and its southwestern margin Transbaikalian basins and Minusa Trough.
We determine a series of key paleomagnetic poles for, and This quantitative approach provides the opportunity for a general revision of Mesozoic tectonics of Central Asia. Many researchers have considered the Eurasian continent to have been completely stable during the Mesozoic era. However, we demonstrate systematic deviations of corresponding Mesozoic poles from Siberia and Europe, and interpret the discrepancies as evidence for large-scale sinistral strike-slip motion due to clockwise rotation of the Siberian plate relative to the European plate.
We conclude that, following its Late Paleozoic assembly, the Eurasian plate was not internally stable, i. The Mesozoic geological evolution of Siberia was dominated by strike-slip tectonics. Rift-related grabens formed within the basement of the West Siberia sedimentary basin and orogenic events occurred along the southwestern margin of the Siberian craton, within the Central Asia tectonic province.
Our paleomagnetic reconstruction indicates also that the Mongol-Okhotsk Ocean was still not closed completely before the end of the Jurassic. We propose that final collision occurred in the Early Cretaceous, and during the Middle to Late Jurassic interval, northward subduction of oceanic lithosphere resulted in oblique, west-to-east ocean closure a "scissors-like" model.
The closure was controlled by significant sinistral strike-slip motion of the Siberian craton.
This process is reflected in Transbaikalia by extensive bimodal volcanic activity and development of rift-related structures, including pull-apart basins.
Westart from the end of Mesoproterozoic where the Rodinia supercontinent was assembled. The available geological and paleomagnetic data set suggests that at the Meso-Neoproterozoic boundary Siberian craton was a part of Rodinia supercontinentlengthening the Laurentia northward. The reconstruction implies that the southern inmodern coordinates margin of Siberia was oriented towards the northern margin of Laurentia. Most likely Siberia represented a giant promontory in the southeast of Rodinia,because during the Late Mesoproterozoic and Early Mesozoic, the western, northern andeastern in modern coordinates margins of Siberia represented marginal marine basinsopened to the ocean.
New paleomagnetic data show that the Siberia - Laurentiadisintegration during the Neoproterozoic Rodinia break-up has developed progressivelyfrom west to east along the southern in modern coordinates margin of the Siberiancraton under the controlling role of strike-slips.
During Neoproterozoic on thebackground of the Rodinia break-up in the west of the Siberian craton, a gradualtransformation of passive continental margin into active continental margin occurred witha development of Late Neoproterozoic island arc systems. All of those processes havedetermined the further tectonic stile of Siberian craton during the Late Precambrian. The stage of accretion of the Neoproterozoic island arc to the Siberianpaleocontinent has been going in pre-Vendian, however, even at the end of Vendian the regime of active continental margin was again resumed at least in the southwesternSiberian plate.
Vendian to Earliest Paleozoic is the next important step in tectonic history of the Siberian plate. Its connecting to dynamics of development of the island arc systemlies along the south to south-western margin of the Siberian continent. Relicts of theseisland arcs formed the framework of the Caledonian structure of the Central Asia foldbelt and appeared on the Altai-Sayan region southwestern frame of Siberian craton. Geological and paleomagnetic data prove that the modern mosaic structure of this frameis the result of deformation of a primary stretching island arc system during its obliqueaccretion to the craton under the large-scale strike-slip conditions.
Late Paleozoic dynamics of crust deformation of the Siberian plate at the stage ofcollision with Kazakhstan Baltica and Kara continents was most likely controlled by deepfaults inherited from Early Paleozoic structure. At the end of the Paleozoic, strike-slipsmovements of tectonic domains within the structure of Eurasian continental plate havetaken place. This key moment in the tectonic history of Siberia has been manifested bythe dramatic trap eruption well known as the Siberian Large Igneous Province.
Paleomagnetic evidence obtained for the Mesozoic of Siberia suggest Mesozoicgeological history of Eurasia to be essentially determined by the strike-slip motions oflarge-scale tectonic domains within its structure. The synthesis of paleomagnetic data onthe Mesozoic of Eurasia justifies a sinistrial strike-slip motion of the assemblage ofSiberian structures relative to the European and North-China ones during the Mesozoic.
This process is reflected by the clockwise rotation of the Siberian domain. Thediscrepancy in paleomagnetic pole positions of deferent domains demonstrate thesystematic character and allow to be revealed the scales of strike-slip motions associatedwith this rotation and to propose a new tectonic model describing the history of theclosure of Mongolo-Okhotsk paleoocean.
The oldest island arc complex of Taimyr: In this paper we provide data on the oldest island arc complex of Taimyr, which was established within the Central-Taimyr accretionary belt. We demonstrate its relationship with the mainly turbiditic back-arc basin complex. U-Pb isotopic data for zircons are presented from a plagiogranite and a plagiorhyodacite, indicating that the island arc formed m. T Nd DM varies from to Ma.
Paleomagnetic investigations performed on the island arc complex rocks showed that the paleomagnetic pole of the island arc is close to synchronous poles, obtained for the south-east of the Siberian craton. Consequently, the island arc whose relicts are preserved in the modern structure of the Three Sisters Lake region was located in close proximity to the Taimyr margin of Siberia at the moment of its formation and could be separated from the continent by a back-arc basin.
The data obtained have a fundamental significance for geodynamic paleoreconstructions in the Arctic sector for the Neoproterozoic. The motion of lithospheric blocks was analyzed in the junction zone between the Eurasian Plate and its surrounding structures.
Its present-day stage was considered using GPS and seismologic data. Models of the movement of a rigid plate are considered for Eurasia. A model of Eurasia northern part of Asia was used to determine the rotation parameters of its southern periphery Amur Plate based on GPS data for the Far East Sikhote Alin profileand Transbaikal regions are shown as an example. Paleomagnetic data made it possible to determine the rotation pole of the Siberian Craton relative to its surrounding folded structures during the Mesozoic and to estimate its kinematic parameters.
The permanent position of the rotation pole in the relative coordinate system since the terminal Paleozoic until the Recent indicates a constant rotation velocity of the Siberian domain within the Eurasian Plate structure. Cambrian paleomagnetism in the Bateni Ridge: We present paleomagnetic data on the Cambrian volcanosedimentary complexes of the Bateni Ridge, which correspond to the evolution of the Kuznetsk Alatau island arc. The paleomagnetic poles which served as the basis for the apparent polar-wander path APWP were determined.
The paleomagnetic data were compared with those on the Cambrian poles for other fragments of the Kuznetsk Alatau island arc. The distribution of the paleomagnetic poles suggests that the relative drift of the Kuznetsk Alatau arc fragments and the entire island arc system resulted from large-amplitude strike-slips. In the paleomagnetic record, its accretion is reflected in the coincidence of the Late Cambrian-Early Ordovician poles on the eastern slope of the Kuznetsk Alatau with one another and the coeval poles for the Siberian craton.
Nevertheless, the differences in the position of the poles on the western and eastern slopes of the Kuznetsk Alatau suggest that strike-slip activity along the Kuznetsk-Altai deep fault the major one in the region continued in the Late Paleozoic and, probably, in the Mesozoic. In this paper we present the results of a generalization of paleomagnetic data for the territory of the Siberian craton and its folded framing that were obtained during the last fifteen years. We propose a new version of the apparent polar wander path for the Siberian continental plate, including the interval from the Mesoproterozoic-Neoproterozoic boundary up to the end of the Mesozoic.
The constructed path forms the basis for new concepts on the tectonics of the Siberian paleocontinent and the paleooceans that surrounded it. We present a series of paleotectonic reconstructions based on paleomagnetic data, which not only displays the paleogeographic position of the Siberian continent, but also reveals the features of the tectonic evolution of its margins during the last billion years.
In particular it has been established that large-scale strike-slip motions played an important role in the tectonic regime of the continental plate at all stages of its development. We present new data on the geologic structure and paleomagnetism of the Vendian and Lower Cambrian deposits of the Argun River region in East Transbaikalia.
We discuss the issues related to the recognition of the Argun microcontinent within the composite blocks of the south-eastern part of the Central Asian belt, which are traditionally combined in the Amuria superterrane. Our paleomagnetic determinations help us justify the equatorial position of the sedimentary basin, in which the deposits of the Argun terrane Beletuy and Bystrin formations formed and Ma, close to or directly on the margin of the Siberian paleocontinent.
This data is essential for the reconstruction of the geodynamic evolution of Siberia and Central Asia at the Precambrian- Paleozoic boundary. The kinematics of the Early Caledonian accretion process in the southwest in modern coordinate of the Siberian paleocontinent, and the structure of its active continental margin are debatable subjects.
The large accumulated database finally allows one to find unambiguously interpretable patterns in the distribution of paleomagnetic poles for the analyzed terrane system and to justify numerically the kinematics of the Early Caledonian accretion. In particular, the analysis of paleomagnetic data proves our idea stating that the transformation of the active continental margin in the Cambrian consisted in its breakup and segmentation as well as in the detachment of fragments of the initially whole island arc along a system of sinistral strike-slips during the clockwise rotation of the craton and conform drift of the continental and oceanic lithospheric plates.
It also validates the mostly oblique conditions of the subduction and subsequent accretion, which means a subduction-transform mode on the ocean-continent margin.

We propose a complemented version of the paleotectonic reconstruction for the Cambrian evolution of the Siberian continent western margin, based on the kinematic scheme constructed from paleomagnetic data. The particularities of the current tectonic structure of the Russian part of the Arctic region are discussed with the division into the Barents-Kara and Laptev-Chukchi continental margins. We demonstrate new geological data for the key structures of the Arctic, which are analyzed with consideration of new geophysical data gravitational and magneticincluding first seismic tomography models for the Arctic.
Special attention is given to the New Siberian Islands block, which includes the De Long Islands, where field work took place in Based on the analysis of the tectonic structure of key units, of new geological and geophysical information and our paleomagnetic data for these units, we considered a series of paleogeodynamic reconstructions for the arctic structures from Late Precambrian to Late Paleozoic.
This paper develops the ideas of L. Natapov on the Precambrian Arctida paleocontinent. We consider its evolution during the Late Precambrian and the entire Paleozoic and conclude that the blocks that parted in the Late Precambrian Svalbard, Kara, New Siberian, etc. Yu Concerning the issue of paleotectonic reconstructions in the Arctic and of the tectonic unity of the New Siberian Islands Terrane: However many questions of its structure, borders and formation history are under intense discussion.
During the international expedition in we solved many problems concerning structural geology, paleontology, petrology and geochronology. A particular attention was given to obtaining paleomagnetic data for the sedimentary and igneous rocks of the archipelago. The primary objects of paleomagnetic studies were the Early Paleozoic sedimentary rocks of the Kotelny Anzhu and Bennett De Long islands. In this paper we present new paleontological data, including the first one for conodonts of the New Siberian Islands, which help us to specify the age of the Early Paleozoic deposits of the studied sections.
In these sections we took a series of paleomagnetic samples. The match of the paleomagnetic directions we determined for Bennett Isl. These first paleomagnetic data allow us to affirm that at least from the Early Ordovician the rocks of the Anzhu and De Long archipelagos formed within the same New Siberian Islands terrane, that is to say, on the same basement.
This paper presents the first actual information on the geology of Jeannette Island, one of the islands of the De Long archipelago located in the East Siberian Sea. We show that Jeannette Island has a volcano-sedimentary section dominated by volcaniclastic turbidites. The sequence identified on the southwestern coast of the island has a submonoclinal plunge complicated by secondary deformation structures, which indicate a general E-W direction of tectonic transport in present-day coordinates.
The sequence is intensely cut by multiple thin up to a few meters gabbro-dolerite dikes that are deformed conformably with the host rocks. The general geological framework of the island bears a close resemblance to that of nearby Henrietta Island located some 70 km to the east, which consists of a volcano-sedimentary cover of Early Paleozoic age.
No organic remains have been found in the studied section of Jeannette Island. The preliminary results of isotope geochronological and paleomagnetic studies confirm the Late Precambrian-Early Paleozoic age assigned to the entire rock complex of Jeannette Island.
The measured paleomagnetic directions are generally consistent with the directions of Lower Paleozoic rocks of Bennett Island De Long archipelago and Kotelny Island Anzhu archipelagowhich confirms our earlier conclusion that the New Siberian Islands shared a common tectonic history and that this structural element of the Arctic shelf appears to have been a terrane during the Early Paleozoic.
This new information can help elucidate the possible relations between the marginal-continental, shelf, island and deep-seated structures of the Eastern Arctic. Rhyolite-granite association in the Central Taimyr zone: Evidence of accretionary-collisional events in the Neoproterozoic11The article was translated by the authors. The Central Taimyr accretionary belt includes two granite-metamorphic terranes: Faddey and Mamont-Shrenk, which include the oldest igneous formations of the Taimyr folded area in the Arctic framing of the Siberian craton-granitoids and granite-gneisses with U-Pb zircon ages of Ma.
This paper presents results of new petrographic, geochemical, geochronological, and paleomagnetic investigations of acid rocks from a volcanic-plutonic association in the region of the Leningradskaya River in the Faddey terrane in the northeastern Taimyr area. These rocks formed during the final stage of continent-island arc accretion and collision that occurred at approximately Ma.
We established that the studied rocks belong to a long granitoid belt extending from Mamont-Shrenk to Faddey terrane, where all the igneous bodies are deformed and oriented uniformly. The paleomagnetic pole we calculated differs significantly from the apparent polar-wander path interval of corresponding age for Siberia.
Age of the basement beneath the de long islands New Siberian Archipelago: This paper is a summary of the geological and geophysical information available today on the tectonics of the Arctic continental structures in the Late Precambrian-Paleozoic.
We propose a new outlook on the history of Arctida - a continental mass that combined sialic blocks of the current Eurasian shelf of the Arctic Ocean. Based on new materials including paleomagnetic data we present a series of paleotectonic reconstructions that reflect the main evolutionary stages and mechanisms of the structure of Arctida from the Early Neoproterozoic to the Mesozoic. We demonstrate the role of the continental blocks of the Arctic in the global drift of lithospheric plates from the breakup of Rodinia to the assembly of Pangea.
From the presented model we propose the existence of two! Arctic subcontinents in the Neoproterozoic-Paleozoic history of the Earth. Arctida-I was a collage of ancient blocks of Arctic sialic crust within Rodinia in the junction zone between the Laurentia, Siberia and Baltica cratons. During the breakup of Rodinia this subcontinent was destroyed with the formation of a series of small continental plates such as Kara, Svalbard and, probably, the New Siberian Islands NSIwhich is usually regarded as part of the Chukchi-Alaska composite terrane.
By the time of its breakup Arctida-I was in a subequatorial position. The post-rifting tectonics of the newly formed small plates was closely associated with strike-slips that played a defining role both at the stages of opening and closure of the Paleozoic oceans.
The rebirth of Arctida was due to the assembly of Pangea at the Paleozoic-Mesozoic limit. We consider Arctida-II a newly formed subcontinent that composed the shelf margin of Pangea in the temperate latitudes of the northern hemisphere, and again connected the margins of Laurentia, Baltica and Siberia.
T D, Larionov A. There are continuing issues concerning the formation and reconstruction of the geographic position of the Neoproterozoic Yenisei Ridge-key element of the western framing of the Siberian craton and the Central Asian orogenic belt.
This study focuses on the inner structure, composition, and boundaries of the Central Angara terrane, which is the largest in the Transangarian segment of the Yenisei Ridge. We propose a scheme of fault deformation of the region and demonstrate that the fault tectonics of the Central Angara terrane is distinct from that of adjacent terranes.
We study in detail the Yeruda pluton granitoids of the Teya complex, which indicate accretionary-collisional magmatic events in this terrane prior to its collision with Siberia. Integrated petromagnetic and paleomagnetic investigations yield a paleomagnetic pole that is significantly different from the corresponding Neoproterozoic interval of the apparent polar wander path APWP for Siberia. The difference in paleolatitudes between the Central Angara terrane and the Siberian craton at the time of the Teya granites formation was at least 8.
We consider various possible positions for the terrane relative to the Siberian craton. These results demonstrate that the Ma magmatic events in the Central Angara terrane are not related to events in the western margin of the Siberian craton.
