Mid-ocean ridge in the Labrador Sea
The Mid-Labrador Ridge was a mid-ocean ridge in the Labrador Sea that represented a divergent boundary between the Greenland and North American plates during the Paleogene . The ridge extended from the South Greenland Triple Junction in the southeast to the Davis Strait area in the northwest.[ 1] Seafloor spreading along the Mid-Labrador Ridge discontinued about 40 million years ago when the mid-ocean ridge became essentially extinct.[ 2]
The Mid-Labrador Ridge is now mostly buried under sediment, exposed only as a northwesterly trend of seamounts in the southeastern part of the Labrador Basin.[ 3]
