Abstract

Modern geological and geophysical studies of Central Arctic uplifts area and East-Arctic Shelf has revealed the basic problems in stratigraphic subdivision of sedimentary cover. Basic approach for subdivision of Arctic Ocean sedimentary cover is based on the wave field’s characteristics and tracing of regional seismic horizons. Their age identification still depends on general geological ideas. Different correlative models of seismic-stratigraphic units and their ages are given in this study for different Arctic regions. The following regions were selected for analyses: Cis-polar part of the Lomonosov Ridge and zone of its connection with the Amundsen and the Makarov basins, profile CDP A7, located in the transition zone of the Lomonosov Ridge, the Russian Shelf and the North-Chukchi shelf trough.
