metadata.value: U–Pb and Lu–Hf isotope analyses of detrital zircons collected from the Devonian–Permian strata of Kotel’ny
  Island (New Siberian Islands, Eastern Russian Arctic) provide vital information about provenance areas and
  history of the poorly studied Paleozoic basement of the Laptev and East Siberian shelves. Based on detrital zircon
  signatures, our study reveals that the studied succession can be divided into two distinct groups:
  Devonian–Lower Carboniferous and uppermost Carboniferous–Permian. U–Pb and Lu–Hf isotope signatures of
  detrital zircons from the Devonian–Lower Carboniferous deposits correspond to well-known Precambrian–Early
  Paleozoic magmatic and metamorphic events within the northern part of Baltica, indicative of a peri-Baltican
  affinity of the New Siberian Islands during this time. A lack of zircon ages close to the depositional age of the
  formation, along with a mature composition of the sandstones, suggest that the Devonian–Lower Carboniferous
  succession formed as a result of extensive sediment reworking from a distal provenance. By contrast, uppermost
  Carboniferous–Permian sandstones have an immature composition, with numerous young detrital zircons close
  to the age of sedimentation and Hf signatures typical of a continental arc environment. We therefore suggest that
  the provenance for these younger deposits was located within a coeval orogeny and based on previous studies,
  we conclude that these deposits were sourced from the north-western part of the Uralian Orogen.
