Geologic?l History of E?st Siberi?n Se? Shelf
Safronov, Aleksandr F.
International Journal of Environmental and Science Education, v11 n10 p3956-3970 2016
In our study we discuss the traditional and novel concepts of East Siberian Shelf origin with regards to the structure and composition of the Paleozoic and early Mesozoic sediments, coming to the surface on the Siberian Islands ?rchipel?go. The core idea is to summarize the existing concepts of East Siberian Shelf formation and to draw up the strong theory of its origin. We suggest that before the Middle Paleozoic, the Siberian Islands ?rchipel?go (Novosibirsk unit) was part of the Siberian craton. The formation of the South ?nyui small oceanic basin became one of the key events in the geologic history of this territory. Formation of South ?nyui small oceanic basin is associated with the Late Devoni?n-E?rly Carboniferous rift genesis. During the Late Paleozoic, the passive continental margin was formed on the southern slope of the Novosibirsk unit. After the closure of the South ?nyui Ocean under the influence of Late Cretaceous stretching processes the rift system of the northwestern strike was formed, over which the East Siberian basin was later formed.
