Modern sediments of the eastern part of the Arctic Ocean and their geologic significance

Article preview

Tectonic model of the Arctic Ocean can be described as a system of folded areas and platform structures closely associated and mutually bonded in their long lasted formation. One of the main tectonic elements in the Eastern part of Polar basin is the so-called Hyperborean platform – a relic of the Eastern-Arctic paleoplatform, which previously had occupied the most part of Arctic region, but was destructed during Mesozoic-Cenozoic. The Hyperborean platform and other fragments of the mentioned paleostructure have preserved their initial affinities, all they form the Arctic shelf areas.

Methodological principles of landscape-geoecological studies of the shelf on the example of the Barents Sea

Article preview

In this study is offered the methodology of mapping of geoecological conditions and pollution of the Arctic seas environment based on geochemical zoning. That has found reflection on the maps of the Barents sea. At making up of maps the materials on lithology and mineralogy of bottom sediments, data on the content of chemical elements in deposits and suspensions and information about quantitative distribution and benthos spices structure are used. The characteristics of conditions of natural environment are analyzed in view of features of a bottom relief.
