Abstract
Sea-floor spreading magnetic lineations 25 (59 Ma) and older have been reidentified in the Labrador Sea by using previous magnetic compilations and some recently acquired data. The higher density of these identifications enabled the calculation of a new set of better constrained rotation poles that describes the sea-floor spreading history of the Labrador Sea and Baffin Bay in a way that is somewhat different from previously published reconstructions. The most important inference that emerges from this work is that the change in spreading direction between Greenland and North America after anomaly 25 time is larger than previously recognized. As a result, the position of Greenland at the time of initial opening (92 Ma) may have been about 100 km farther south than obtained in earlier reconstructions.
