“…375 Ma, and another in the latest Devonian, peaking at ca. 365 Ma [10,11]. The basalt flows across our study area in north-eastern Siberia occur within the lowermost Frasnian carbonates, with a tentative age assumption of 383-380 Ma.…”

“…The Devonian Period was characterized by significant tectonic and magmatic events across south-eastern Siberia, which resulted in formation of the Yakutsk-Vilyui large igneous province (LIP) ( [9][10][11][12][13] and references therein). The Yakutsk-Vilyui LIP is a giant radiating mafic dyke swarm and rift basins, converging on an assumed mantle plume center along the eastern margin of the Siberian Craton [11][12][13][14][15][16].…”

“…Coeval carbonatites and kimberlites are associated with the Yakutsk-Vilyui LIP of eastern Siberia, with the Vilyui rift/Vilyui basin representing the main rift basin associated with the LIP across the eastern part of the Siberian Craton [9]. The Yakutsk-Vilyui LIP is one of the largest LIP of the Phanerozoic, exerting a major impact on the tectonic evolution of Siberia and surrounding landmasses and furthermore, possibly exerted a significant global impact on the biota and climate of the Middle-Late Devonian [10].…”

We present new data on the tectonic evolution of north-eastern Siberia using an integrated provenance analysis based on U–Pb detrital zircon dating and sandstone petrography of Devonian sedimentary strata. Our petrographic data suggest that Upper Devonian sandstones of north-eastern Siberia were derived from a local provenance, supported by the widespread distribution of ca. 1900–2000 Ma magmatic events in the basement of the neighboring Ust’-Lena and Olenek uplifts. Devonian detrital zircon age distributions of the Devonian sandstones are similar to ages of Middle Paleozoic magmatic rocks of Yakutsk-Vilyui large igneous province (LIP). Therefore, we suggest that the studied sandstones were derived from proximally-located uplifted blocks composed of Proterozoic–Devonian rocks and Middle–Late Devonian volcanics. Moreover, the abundance of Middle–Late Devonian zircons is suggestive of a wider distribution of coeval magmatism across north-eastern Siberia than previously supposed. We propose that widespread Devonian magmatism associated with the Yakutsk-Vilyui LIP also occurred to the east of our study area and is now buried beneath thick Carboniferous–Jurassic sedimentary rocks of the eastern Siberian passive margin, subsequently deformed into the Late Jurassic–Cretaceous Verkhoyansk fold-and-thrust belt. We also propose that the major pulse of the Yakutsk-Vilyui LIP occurred in north-eastern Siberia during the Middle Devonian at ca. 390 Ma, some 15 million years earlier than within the Vilyui rift basin in eastern Siberia (ca. 375 Ma).

“…Moreover, LIPs often precede the main extinction intervals, which can be explained by delayed ecosystem responses, because volcanism leads to climatic changes (warming) 7 (the press-pulse volcanic model; 7 ). According to Ernst et al 76 , a second main pulse of the Kola-Dnieper and Yakutsk-Vilyui LIPs occurred around 360 Ma, which may be tentatively correlated with previous Famennian ocean anoxic episodes such as the Annulata or Dasberg Events and/or the Hangenberg Crisis.…”

“…One of the problems with the volcanism hypothesis is a lack of precisely dated Large Igneous Provinces (LIP) during this time interval ( 74 , for details see 7 ). Nevertheless, the activity of the continental silicic Maritimes (Magdalene) LIP in eastern Canada includes the 360–370 Ma interval, with a pulse at around 360 Ma 75 , 76 . Moreover, LIPs often precede the main extinction intervals, which can be explained by delayed ecosystem responses, because volcanism leads to climatic changes (warming) 7 (the press–pulse volcanic model; 7 ).…”

Recently, the end-Devonian mass extinction (Hangenberg Crisis, 359 Ma) was identified as a first-order mass extinction, albeit not one of the “Big Five” events. Many marine and terrestrial organisms were affected by this crisis. The cause of this mass extinction is still conjectural and widely discussed. Here we report anomalously high mercury (Hg) concentrations from the South Tian Shan (Uzbekistan), together with correlation using conodont biostratigraphic data. Hg enrichment (to 5825 ppb) was detected in marine deposits encompassing the Hangenberg Crisis. In the Novchomok section, the Hangenberg Crisis interval does not contain typical Hangenberg Black Shales; however, by means of inorganic geochemistry (enrichment of redox-sensitive elements such as Mo, V, and U) we detected an equivalent level despite the lack of marked facies changes. This is the first record of Hg and Hg/total organic carbon anomalies in marly shales, marls and carbonates that are totally independent of facies changes, implying that volcanism was the most probable cause of the Hangenberg Crisis. This conclusion is confirmed by the presence of a negative δ13C excursion, which may reflect massive release of isotopically light carbon from volcanogenic and thermogenic devolatilization likely combined with increased arc-volcanism activity worldwide at the end of the Devonian.

Large igneous provinces are voluminous (> 0.1 Mkm 3 ( = 10 6 km 3 ); frequently above 1 Mkm 3 ), mainly mafic (ultramafic) magmatic events of intraplate affinity (based on tectonic setting and/or geochemistry) that occur in both continental and oceanic settings, are often linked with mantle plumes, and are typically emplaced over a short time period ( < 5 myr; often < 2 myr) or in multiple short pulses with a maximum duration of a few tens of myr (e.g.,
