Geologic and geophysical observations in the northern Labrador Sea

ABSTRACT. Recent investigations have yielded valuable information as to the morphology, structure and origin of the northern Labrador Sea. Indirect evidence indicates bottom current regimes may well control the dynamic processes of sedimentation. The buried Mid-Labrador Sea Ridge was traced to the s...

Description
Summary:ABSTRACT. Recent investigations have yielded valuable information as to the morphology, structure and origin of the northern Labrador Sea. Indirect evidence indicates bottom current regimes may well control the dynamic processes of sedimentation. The buried Mid-Labrador Sea Ridge was traced to the sill of Davis Strait. It is postulated that this ridge represents a relic Mid-Oceanic Ridge which through axial growth separated the continental blocks of Greenland and Canada. RESUME. Observations gkologiques et gdophysiques duns le nord de la mer du Labrador. Des recherches rCcentes ont fourni de prkcieuses informations sur la morphologie, la structure et l’origine de la partie nord de la mer du Labrador. Des preuves indirectes indiquent que les rCgimes des courants de fond pourraient bien dkterminer les processus dynamiques de skdimentation. La crEte enfouie au milieu de la mer du Labrador a 6th retracCe jusqu’au seuil du dCtroit de Davis. On peut considkrer que cette cr&te reprksente les restes d‘une crEte mkdi-ockanique dont la croissance axiale a sCpark les blocs continentaux du Groenland et du Canada.
