    Increased sediment supply is also recognized in the Barents Sea Basin at this time, not only from Fennoscandia along the northern margin (this study), but also from Greenland to Spitsbergen (e.g., Wignall et al., ), and from the Kara Sea and the Urals to the greater Barents Sea Basin (e.g., Puchkov, ; Glørstad-Clark et al., ). In Cited by: The western Barents Sea is characterized by broad platform areas cut by fairly narrow rifts. In contrast, the eastern Barents Sea is a very broad and deep sag basin with little internal structuring. Glacial climate changes over the last million years have influenced the distribution of .

    The geology of the region, which still today represents exploration frontiers, is illustrated by a series of geophysical and paleogeographic maps, which are based on the integrated knowledge from Russian and Norwegian institutions. The paleogeographic map span from the Early Devonian to Eocene times, and are supplemented by geophysical maps and cross-sections showing the present day architecture. The SW Barents Sea margin experienced a pulse of extensional deformation in the Middle–Late Devonian through the Carboniferous, after the Caledonian Orogeny terminated. These events marked the initial stages of formation of major offshore basins such as the Hammerfest and Nordkapp by: 8.

NE-SW grain of the southwestern Barents Sea and Finnmark. The major basins of the Russian Barents Sea parallel the N-S Uralian grain of the Novaya Zemlya chain. The Late Palaeozoic and Mesozoic tectonic history of the Barents Sea was dominated by extensional tectonic move-ments, at first representing the collapse of the newly formed.

The southern half of the Barents Sea, including the ports of Murmansk (Russia) and Vardø (Norway) remain ice-free year round due to the warm North Atlantic September, the entire Barents Sea is more or less completely ice-free.

The northeastern part of the Varanger Peninsula (Barents Sea region, Fig. 1) is underlain by about 9 km of Neoproterozoic, deep-to shallowmarine sedimentary rocks, a succession that was deformed.

A description of the systems and patterns of faulting in Caledonide Finnmark and the southernmost Barents Sea has been presented by Lippard and Roberts ().In brief, NW–SE- and NE–SW-oriented faults dominate the map-picture both on land and offshore ().Although dip-slip normal offsets predominate, and probably relate to Late Palaeozoic to Mesozoic crustal extension, significant Cited by: Extensional tectonic history of the western Barents Sea C.A.

The Barents Sea is a part of the Arctic region, comprising areas of different geological evolution caused by several large-scale tectonic adjustments. The interaction of the Baltica, Laurentian and Siberian plates, together with smaller continental blocks, is the basis for the formation of the current Barents shelf crust (Marello et al.

The Barents Sea is a substantial part of this region covering more than million km 2 in the northern European Arctic ().The western half exhibits a complex tectonic structure made of a fan-shaped array of sedimentary basins and basement horsts and a brittle.

This paper reviews the exploration history of the Barents Sea part of the Norwegian continental shelf. The main structural elements which so far have been identified in the Troms/Finnmark/Barents Sea region are outlined and discussed.

Special attention is given to the selected Area I outside Troms, where according to latest government plans, drilling will start in Cited by: This thesis describes the structural and stratigraphical evolution of the Fingerdjupet Subbasin.

Structural and stratigraphical interpretation has been performed in both 2D and 3D, both on paper and with software, to identify and map out important phases of tectonic activity in the study area and link it to the depositional patterns.
