Stratigraphy of the Labrador margin: a synthesis and new perspectives
2022The Labrador Sea formed during rifting between North America and Greenland beginning in the Early Cretaceous, with subsequent seafloor spreading from the Maastrichtian (chron C31) to Early Paleocene (chron C27n) that ended by chron C13 (earliest Oligocene).

New Insights into the Tectonostratigraphic Evolution of the Labrador Margin
Offshore Technology Conference, 2010Abstract To support the renewed interest in the hydrocarbon potential of the Labrador Sea, we have completed a regional seismic interpretation and integrated this with new biostratigraphic data, based on analyses of palynomorphs from wells in the Hopedale and Saglek basins.

Wide‐angle seismic studies have determined the detailed velocity structure along a 350‐km‐long profile across the Labrador margin. Combination of this model with a previously published cross section for the southwestern Greenland margin constitutes the first combined conjugate margin study based on seismic velocity structure. The results indicate three

New evidence on the structure of the Labrador Sea/Greenland continental margin
Journal of the Geological Society, 1991A 275 km section of a regional seismic reflection profile from the Greenland side of the Labrador Sea has been reprocessed and interpreted. Three zones of different structural style have been identified, the innermost of which is block-faulted. Magnetic modelling based on the seismic line shows that sea-floor spreading anomalies are confined to the ...

Abstract The stratigraphic record along the continental margin of Labrador and Newfoundland provides ample evidence for vertical movements both prior to and after break-up. In the offshore domain, several major hiatuses punctuate the stratigraphic record.

Continental slope sedimentation adjacent to an ice margin. III. The upper Labrador Slope
Marine Geology, 1999Abstract The upper Labrador Slope is the key area for sediment transfer from the northeastern margin of the Pleistocene Laurentide ice sheets (LIS) to the deep basin. It is subdivided from north to south into 8 sectors based on relief differences and echo-character on 750 line-km of continuous sleeve-gun and 3.5 kHz seismic profiles.

Abstract In western Labrador, the northern margin of the Grenville Province, known as the Grenville Front Tectonic Zone, abuts against the Superior Foreland zone composed of an Archean gneiss terrain, and against the Churchill Foreland Zone composed of weakly metamorphosed and deformed Aphebian supracrustals.

Seabed evidence for a south-flowing ice shelf along the Newfoundland and Labrador margin
Un nouveau concept de régime glaciaire marin a émergé de la récente cartographie géologique superficielle régionale. Des images bathymétriques à plus haute résolution révèlent des linéations érosives orientées nord-sud et une moraine du bord du plateau, qui constituent toutes deux des preuves solides de la présence d'une plate-forme de glace le long deG.

Development of the continental margins of the Labrador Sea: a review
Geological Society, London, Special Publications, 2001AbstractThe Labrador Sea is a small oceanic basin that developed when the North American and Greenland plates separated. An initial period of stretching in Early Cretaceous time formed sedimentary basins now preserved under the continental shelves and around the margins of the oceanic crust. The basins subsided thermally during Late Cretaceous time and
