metadata.value: An integrated provenance analysis based on sandstone petrography, distribution of REE and trace elements,
  and U/Pb detrital zircon dating of Carboniferous sedimentary rocks of northern Verkhoyansk
  Fold and Thrust Belt (FTB) provides new insights into the tectonic evolution of NE Siberia. According to
  petrographic and geochemical data, Lower Visean sandstones had local provenance that contained mafic
  magmatic rocks. Wide distribution of ca. 2075 Ma detrital zircons known in the basement of neighboring
  Olenek and Ust’-Lena uplifts supports local provenance of the Lower Visean sandstones. Starting from Late
  Visean, clastic sediments have geochemical and petrographic compositions that are characteristic for erosion
  predominantly felsic rocks in a more remote source region. Detrital zircon age distributions in the
  Upper Visean – Upper Carboniferous sandstones, point to Taymyr – Severnaya Zemlya FTB and Central
  Asian Orogenic Belt (CAOB) as the most likely provenances for clastic rocks. However, wide distribution
  of Neoproterozoic and early Paleozoic detrital zircons that are not typical for synchronous
  CAOB-derived clastic rocks in the West Verkhoyansk, provide evidence for other than CAOB source area.
  We infer that the most likely source for Neoproterozoic – early Paleozoic detrital zircons in the Upper
  Visean – Upper Carboniferous sandstones is the Taimyr-Severnaya Zemlya FTB. The shift to sources from
  the Taimyr-Severnaya Zemlya FTB suggests an earlier (Late Visean) age for the collision between Kara terrane
  and Siberia than has been previously assumed (Late Carboniferous – Permian). Our paleogeographic
  restoration reveals the existence of two major fluvial systems draining eastward across the Siberian Craton
  during the Carboniferous: the Paleo-Lena in the south and the Paleo-Khatanga in the north.
