A study of large-scale basins and comparison to the Eastern Barents Sea basins
Detailed study of the gravity field and the isostatic state of the Barents Sea Region shows that the Eastern Barents Sea basins are not typical rift basins. They show distinctive features as large wavelengths, high lithospheric mantle density, thick sequence of sediments, a flat Hoho and high elasti...

Detailed study of the gravity field and the isostatic state of the Barents Sea Region shows that the Eastern Barents Sea basins are not typical rift basins. They show distinctive features as large wavelengths, high lithospheric mantle density, thick sequence of sediments, a flat Hoho and high elastic thickness, which are normally associated with cratonic or intracratonic basins. To understand the underlying cause of the Eastern Barents Sea basins, we make a comparison to well studied cratonic basins. For these basins, the structure, subsidence history and temperature evolution is relatively well known. We study the West Siberian basin, as an adjacent large-scale basin, the Michigan basin in North America, the Solimoes, Amazon, Parnaiba and Parana basins in South America, the Tarim basin in Central Asia and the Congo basin in Africa. The analysis includes the characterization in terms of gravity signal, geoid undulations, isostatic state, age and igneous activity. 52800 |
