| Abstract | The stratigraphy and the geological evolution of the West Greenland margin from the Labrador Sea to Baffin Bay in both the onshore and offshore areas are described. The primary data sets include seismic
reflection surveys, wells, and outcrops. In addition, seabed samples, seismic refraction and magnetic data, onshore and offshore maps, and stratigraphic compilations were used. The basins of the West Greenland continental margin are described in
three regions from the south to the north: southern West Greenland basins, central West Greenland basins, and northern West Greenland basins. Each region includes a description of the stratigraphy and evolution from the Archean to the Quaternary,
divided into six phases: pre-rift and early extension, early rift, subsidence and rifting, late rift, drift, and post-drift. Finally, the regions are correlated and described in a tectonostratigraphic context together with analogues from the Canadian
conjugate margin. |
| Summary | (Plain Language Summary, not published)
The stratigraphy and the geological evolution of the West Greenland margin from the Labrador Sea to the Baffin Bay in onshore and offshore areas is
described. The basins of the West Greenland continental margin are described in three regions from the south to the north: (1) southern West Greenland basins, (2) central West Greenland basins and (3) northern West Greenland basins. Each region
includes a description of the stratigraphy and evolution from the Archean to the Quaternary, divided into six phases: (1) Pre-rift/initial extension, (2) Early rift, (3) Subsidence-rift, (4) Late rift, (5) Drift, and (6) Post-drift. Finally, the
regions are correlated and described in a regional geological context together with analogues from the Canadian conjugate margin. |
