The geology of North-East Greenland (70–78°N) exposes unique evidence of the basin development between the Devonian collapse of the Caledonian Orogen and the extrusion of volcanics at the Paleocene–Eocene transition during break-up of the North-

Uplift and volcanism drove fragmentation of the Norwegian-Greenland seaway, which may have restricted Arctic-Atlantic exchange during the Paleocene-Eocene Thermal Maximum, according to sedimentological, paleontological and seismic analyses from NE Gr

Abstract Volcanostratigraphic and igneous province mapping of the Jan Mayen microcontinent (JMMC) and Iceland Plateau Rift (IPR) region have provided new insight into the development of rift systems during breakup processes. The microcontinent's form

The rupture of continents and creation of new oceans is a fundamental yet primitively understood aspect of the plate tectonic cycle. Building upon past achievements by ocean drilling and geophysical and geologic studies, we propose “The Continental

Baffin Bay formed as a result of continental extension during the Cretaceous, which was followed by seafloor spreading and associated plate drift during the early to middle Cenozoic. The formation of an oceanic basin in the central part of Baffin Bay

Large structural highs and sedimentary basins are identified from mapping of the West Greenland continental margin from the Labrador Sea to the Baffin Bay. We present a new tectonic elements map and a map of thickness from the seabed to the basement
