metadata.value: The first Sm–Nd isotope studies of the Carboniferous–Early Cretaceous clastic rocks of the northeastern Siberian Platform have been carried
  out. Variation in the isotope composition of sediments within this time interval has been determined and interpreted. The high εNd(t) values
  for Carboniferous–Permian sediments (from –11 to –2) testify to the large contribution of the products of erosion of island-arc and juvenile
  complexes localized in the Taimyr–Severnaya Zemlya fold–thrust belt in the Carboniferous. The positive εNd(t) values for Triassic sandstones
  suggest erosion of the coeval igneous rocks of the trap association. The Upper Jurassic and, particularly, Cretaceous sediments of the
  Lena–Anabar depression and Verkhoyansk foreland basin are characterized by extremely negative εNd(t) values (from –15 to –19), which is
  evidence for erosion of mature continental crust. The Carboniferous–Triassic complexes of the Verkhoyansk fold–thrust belt, which show
  higher εNd(t) values, cannot have been a source of detritus for Cretaceous sandstones. The sediments filling the Verkhoyansk foreland basin
  accumulated as a result of the decomposition of homogenized distal source rocks with the isotope characteristics of the old crust rather than
  the breakup of the mountain range rising to the east. Salients of the crystalline basement of the Siberian Platform, such as the Aldan Shield,
  might have been these source provinces
