На основе анализа гидрографических материалов выделены формы рельефа северного шельфа Евразии, определены их возраст и генезис, описаны шесть этапов развития рельефа в миоцен-антропогеновое время, связанные с колебаниями уровня Мирового океана, и следы двух оледенений (плиоценового и позднеплейстоценового) в Евразийском секторе шельфа.
At the northern continental shelf of Eurasia a submerged network of branching valleys still exists, which was formed between Miocene and Pliocene under conditions of the Ocean level lowering not less than 300 meters below the present one. Later on the valley pattern was slightly changed in connection with Early and Late Pleistocene regressions. The Pliocene-Pleistocene and Late Pleistocene trangressions resulted in the «flight» of graded abrasion-accumulative surfaces at the shelf. Two glaciations (in Pliocene and Late Pleistocene) can be distinguished at the submarine margin of Norway and northern archipelagos of the Eurasian Arctic shelf.
The authors declare that there are no conflicts of interest present.
