GEOMORPHOLOGY OF THE BERING ISLAND COASTAL AREA
Valery Bykasov and Galina Chujan
The Bering Island is an elongated from south-east to north-west and tectonically upstanding block of a shelf platform that, in its turn, forms the top of a subaqueous ridge of a western part of the Aleutian island volcanic arc. The greater part of the island is occupied with a middle-high ridge (from 150 up to 750 m) that stretches from CapeMonati in the south-east to the depression of LakeSarannoe. This ridge is distinctly subdivided into two morphological parts by the watergap of the Polovinnaya and Peresheek rivers. The ridge relief is mainly denudational-tectonic. This is emphasized by a high (up to 100-250 m) shore cliff steeply breaking at the coast.
The history of development of the islands is rather peculiar. There was repeatedly observed sometimes decrease of their area, sometimes, on the contrary, its increase in several times. Anyhow, even in the second phase of Recent Pleistocene glaciation the Bering and MednyIslands represented the united land the coast line of which lay […]
