Abstract Two dolerite dyke swarms are recognized along and paralleling the Ural Mountains, Russia. The Uralian swarm is 1400-km long (2300-km long if traced from its inferred plume centre). Further north, the Pay-Khoy swarm can be traced through the Pay-Khoy–Novaya Zemlya fold belt for a distance of c. 250 km (800-km long if traced from its inferred plume centre). An Upper Devonian age for volcanism associated with the Pay-Khoy swarm is well constrained by isotopic data. A Devonian age for the… Expand
Tectonic implications of the lithospheric structure across the Barents and Kara shelves
Abstract This paper considers the lithospheric structure and evolution of the wider Barents–Kara Sea region based on the compilation and integration of geophysical and geological data. RegionalExpand
Unique Rhenium Deposit in the Carboniferous Coal-bearing Sands of the Russian Plate: Communication 1. Geological Structure
Abstract The Briketno-Zheltukhinskoe U–Mo–Re deposit is located in the southern sector of the Moscow lignite basin (central East European Platform). It is restricted to the paleochannel and deltaicExpand
A volcanic scenario for the Frasnian–Famennian major biotic crisis and other Late Devonian global changes: More answers than questions?
Abstract Although the prime causation of the Late Devonian Frasnian–Famennian (F–F) mass extinction remains conjectural, such destructive factors as the spread of anoxia and rapid upheavals in theExpand
Late Devonian paleogeography in the framework of global plate tectonics
Abstract This paper presents Late Devonian (Frasnian–Famennian) global and regional paleogeographic maps displaying present day coastlines, tectonic elements' boundaries, subductions, rifts,Expand
Magmatic complexes of the Urals as suspect parts of Large Igneous Provinces
Petrogenetic, geochemical studies and isotope age determinations of flood basalts, dolerites, trachybasalts, picrite-basalts, rapakivi granites, layered mafic-ultramafic intrusions and also alkalineExpand
The importance and difficulties of identifying mantle plumes in orogenic belts: An example based on the fragmented large igneous province (LIP) record in the Ural fold belt
Abstract Mantle plumes can be recognized by their magmatic expression as large igneous provinces (LIPs). However, identification of plumes in old, structurally complicated fold belts is particularlyExpand
Age correlation of Large Igneous Provinces with Devonian biotic crises
Abstract Large Igneous Provinces (LIPs) are emerging as a significant driver of short duration climatic change including mass extinctions. Here we compare the record of LIPs against the timing ofExpand
Results of U–Pb dating of zircons from wehrlite of the platinum-bearing Feklistov massif (Shantar Archipelago, Russia)
The compositional and isotope–geochemical features of zircons from wehrlite of the Feklistov massif, which formed platinum coastal placers, are discussed in this paper for the first time. ZirconsExpand
Mercury Anomalies Link to Extensive Volcanism Across the Late Devonian Frasnian–Famennian Boundary in South China
The Late Devonian Frasnian–Famennian (F–F) mass extinction has been long-time debated by non-volcanic causes, extra-terrestrial impacts, and large igneous province (LIP) eruptions. To betterExpand
General features relating to the occurrence of mineral deposits in the Urals: What, where, when and why
Abstract This study of metallogeny of the Urals is strongly tied up with a stage-by-stage geodynamic analysis of the orogen. The analysis includes a revised understanding of geodynamic development ofExpand


Radiating rifts and dyke swarms of the middle Paleozoic Yakutsk plume of eastern Siberian craton
Abstract The eastern part of the Siberian craton is locus to a mid-Paleozoic large igneous province (LIP) distributed over an area of >0.7 × 10 6  km. This Yakutsk LIP originated from a mantle plumeExpand
Magmatism and the geodynamics of rifting of the Pripyat-Dnieper-Donets rift, East European Platform
Abstract The distribution of volcanism in the Late Devonian Pripyat-Dnieper-Donets rift within the East European Platform, based upon the results of deep drilling, indicates that pre-existingExpand
Middle Paleozoic basaltic and kimberlitic magmatism in the northwestern shoulder of the Vilyui Rift, Siberia: relations in space and time
Abstract A Middle Paleozoic tectonothermal event in the eastern Siberian craton was especially active in the area of the Vilyui rift, where it produced a system of rift basins filled withExpand
Cenozoic magmatism throughout east Africa resulting from impact of a single plume
The geology of northern and central Africa is characterized by broad plateaux, narrower swells and volcanism occurring from ∼45 Myr ago to the present. The greatest magma volumes occur on theExpand
Late Palaeozoic intra- and pericratonic basins on the East European Craton and its margins
Abstract The (Mid-) Late Devonian to Early Carboniferous was a time of widespread rifting on the East European Craton (EEC) and its margins. The most prominent basin among these and, accordingly, theExpand
Role of the tectonomagmatic factor in formation of giant hydrocarbon accumulations in the East Barents basin
In terms of tectonics, the East Barents basin(megabasin) represents an extended (~1400 km)wedgeshaped ~500 to 300kmwide structure thatcrosses the West Arctic continental–marginal platform in theExpand
