Abstract

The relief development of the East Arctic shelf during the Cenozoic directly resulted from the Arctic Ocean formation and can be subdivided into four stages| second half of Paleocene to Early Oligocene| Middle Oligocene to Early Miocene| Middle-Late Miocene| Pliocene-present day. Each stage duration was about 12 to 15 mln years with the exception of the last one which has not yet been completed. In each stage a marine transgression reflects changes in the structural plan which include transformation and growth of the area of the subsidence and associated uplift to regional barriers between the basins. Other events : ice cover formation in the polar basin| seasonal freezing of the ground| permafrost developed since the Middle Pliocene
