“…These geological similarities include lithology and faunal assemblages in the sedimentary succession (Cherkesova 1975;Dumoulin et al 2002;Bogdanov 2004;Cocks & Torsvik 2011;Danukalova et al 2014b), the occurrence of Siberian trap flood basalts in the New Siberian Islands (Kuzmichev & Pease 2007), and an inferred Taimyr source for Triassic(?) sandstone on Big Lyakhov island (Miller et al 2013).…”

U-Pb detrital zircon results from New Siberian Islands sandstones illuminate the long-lived controversy regarding the continuation of the Uralian orogen into the Arctic region. A dominant age peak of c. 285 Ma from Permian sandstone requires proximal derivation from Taimyr's CarboniferousPermian granites, thought to reflect syn-to post-tectonic Uralian magmatism. The provenance of Devonian sandstone has Baltica affinities. The data record a dramatic change in provenance between Devonian and Permian time, from Baltica to a mixed Baltica + Uralian source. Our results confirm that the Uralian foreland basin extended from Taimyr to the New Siberian Islands.Supplementary material: Sample co-ordinates, sediment petrography and heavy mineral analysis, U-Pb data tables and description of analytical methods associated with detrital zircon and granite analyses are available at

“…32). In both regions the upper Cambrian -Lower Ordovician (Tremadocian) black shales with subordinate carbonate rocks overlie the middle Cambrian (Mayan) variegated clay-carbonate unit (Danukalova et al 2014). The younger part of the Central Taimyr Ordovician succession differs from that of Bennett Island.…”

“…The upper Cambrian and the lowermost Ordovician rocks on Bennett Island comprise a single succession of at least 250 m thickness, which is dominated by black shale. The name Dunbar Formation has been proposed for it (Danukalova et al 2014). We refer to its upper portion as the Lower Unit of the Ordovician section.…”

“…We refer to its upper portion as the Lower Unit of the Ordovician section. The exact position of the boundary between two systems could not be proven: the distance between the last point with the upper Cambrian trilobites (Aksai Stage, Danukalova et al 2014) and the first occurrence of the Ordovician graptolites is about 600 m along the coast. This interval corresponds to c. 130 m of the true section's thickness (estimated geometrically).…”

Ordovician turbidites and black shales of Bennett Island (De Long Islands, Russian Arctic), and their significance for Arctic correlations and palaeogeography

Bennett Island stands alone in a remote part of the Arctic and information on its geology is essential to ascertain relations with other terranes in order to restore the early Palaeozoic Arctic palaeogeography. Lower Palaeozoic sedimentary rocks throughout the island were studied thoroughly for the first time. The Ordovician section (> 1.1 km thick) comprises three units: Tremadocian, lowest Floian black shale (130–140 m); Floian, lower Dapingian carbonate turbidite (> 250 m); and Dapingian, lower Darriwilian siliciclastic turbidite (> 730 m). Ordovician deposits conformably overlie Cambrian rocks deposited within the Siberian shelf, as shown earlier. Most of the Ordovician succession was formed in a deep trough that received carbonate debris from a nearby carbonate platform and silicate material from a distant landmass located to the NE (present coordinates). The Bennett Island Ordovician rocks have much in common with those of both the Central and Northern Taimyr belts. It could be tentatively suggested that both belts merged at their eastern continuation in the vicinity of De Long Islands. The whole system probably extends further eastwards. The Ordovician facies patterns and faunal assemblages in the New Siberian Islands are notably similar to those of northwestern Alaska, where the same lateral transition from turbidites to shelf limestones was reported.

“…The eastern islands are mostly composed of sedimentary rocks of CambrianeCenozoic age; some magmatic rocks are present on the Bennett, Zhokhov and Henrietta islands. A continuous, weakly deformed marine Cambrian section was described on Bennett Island (Danukalova et al, 2014). Ordovician rocks on Kotelny Island most likely consist of shallow-water carbonates.…”
