The paper describes Meso- and Neoproterozoic rocks from the south part of the East-Anabar Basin. Based on lithological, isotopic and geochemical datawe established that provenance area included predominantly metamorphic rocks of the Anabar Shield. The formation of Riphean sandstones and conglomerates was related to erosion of Daldyn terrane. At the beginning of Vendian time the provenance area was displaced eastward and included Birecte granite-greenstone terrane. Hydrothermal alteration is supposed to be Mesozoic.
