metadata.value: We present new LA ICP-MS U-Pb-Hf detrital zircon data from Neoproterozoic sedimentary basins located along
  the south-western margin of the Siberian Craton. In the Yenisey Ridge (the Taseeva basin), siliciclastic sedimentary
  units contain abundant 2.7–2.5 Ga, 2.0–1.75 Ga and 0.95–0.57 Ga detrital zircon populations, whereas
  for the Prisayan Uplift slightly different detrital zircon ages of 3.0–2.5 Ga, 2.2–1.8 Ga and 0.95–0.65 Ma are
  common. Mid Neoproterozoic sandstones were deposited in a rift setting or along a rifted cratonic margin facing
  a back-arc basin, whereas the immature to submature upper Ediacaran to Lower Cambrian fluvial successions
  were probably deposited in the foredeep setting, at the expense of proximal Neoproterozoic igneous suites and
  the underlying metasedimentary basement. A range of εHf values from −10 to +14 indicates intense mixing
  between juvenile and evolved magma components in a continental arc setting at ca. 950–570 Ma. Geological
  evidence, persistent input of detrital zircon material derived from ancient crustal units of western Siberian
  cratonic margin and evolution of Hf isotopic compositions suggest that the Neoproterozoic arc system of the
  Yenisey Ridge and, partly, Sayan orogens developed along the active margin of Siberia. In the Neoproterozoic,
  the arc system probably extended along the periphery of Rodinia into the Taimyr orogen of northern Siberia and
  Valhalla orogen of north-eastern Laurentia.
