Reply to comment by Denyszyn and Halls (this volume) on “Geological and geophysical observations in the Kane Basin preclude the presence of a major plate boundary in southwestern Nares Strait”

Abstract

The Paleogene movement of the Greenland Plate relative to North America took place in two stages. The movement of the Eocene stage is highly constrained by the known geometry of magnetic lineations and fracture zones in Labrador Sea and Baffin Bay. This geometry requires that the link from Baffin Bay to the Eurekan Orogeny must have been distributed deformation in the Canadian Archipelago, effectively forming an "Ellesmerian" microplate. Geophysical/geological observation in southwestern Nares Strait means that the strike-slip movement of Greenland relative to North America during the Paleocene cannot have been through the Kane Basin but must have taken place farther northwest, probably within the Eurekan Fold Belt.
