N2 - © 2015 Taylor & Francis.Detrital zircon U/Pb ages provide new insights into the provenance of Upper Devonian-Permian clastic rocks of Belkovsky Island, within the New Siberian Islands archipelago. Based on these new data, we demonstrate that Upper Devonian-Carboniferous turbidites of Belkovsky Island were derived from Grenvillian, Sveconorwegian, and Timanian sources similar to those that fed Devonian-Carboniferous deposits of the Severnaya Zemlya archipelago and Wrangel Island and were probably located within Laurentia-Baltica. Detrital zircon ages from the lower Permian deposits of Belkovsky Island suggest a drastic change in provenance and show a strong affinity with the Uralian Orogen. Two possible models to interpret this shift in provenance are proposed. The first involves movement of these continental blocks from the continental margin of Laurentia-Baltica towards the Uralian Orogen during the late Carboniferous to Permian, while the second argues for long sediment transport across the Barents shelf.
