Evolution of the Labrador Sea
The age and spreading rate of the Labrador Sea have been computed from the basement bathymetry. The data give a time of termination of opening 48 m.y. ago and a mean spreading rate of 0.64 cm per year, in good agreement with previous estimates from magnetic data. The shallow depths in the Labrador S...

| Summary: | The age and spreading rate of the Labrador Sea have been computed from the basement bathymetry. The data give a time of termination of opening 48 m.y. ago and a mean spreading rate of 0.64 cm per year, in good agreement with previous estimates from magnetic data. The shallow depths in the Labrador Sea must be accounted for by assuming that the present Iceland hot spot or mantle plume was located under Davis Strait, to the west of Greenland during the opening. A model is proposed for the separation of Greenland from Europe and Canada driven by this plume. |
