THE CAMBRIAN BALTICA-ARCTIDA COLLISION, PRE-URALIDE-TIMANIDE OROGEN, AND ITS EROSION PRODUCTS IN THE ARCTIC

Abstract

Researchers have obtained in the last decade a considerable amount of new data on various aspects of the geological setting of high-latitude regions of the Arctic and northern regions of Russia. These data have made it possible to revise the tectonic scenario of the Late Precambrian–Cambrian evolution of the northeastern and eastern framing of the East European Craton (EEC). Collision of two Late Precambrian continents - Baltica (Neoproterozoic skeleton of the East European Craton) and Arctida — at the Late Precambrian/Cambrian boundary is the key issue in this scenario.
