In the North-East Atlantic, oceanic crust was created continuously from the late Paleocene to the present, forming the Irminger and Iceland basins south-west and south-east of Iceland, respectively, and the Greenland and Lofoten basins north-west and north-east of the Jan Mayen fracture zone complex (Figure 1.1). Based on a growing database of geophysical data many authors have proposed several kinematic models for these basins (e.g., Skog- seid and Eldholm, 1987; Srivastava and Tapscott, 1986; Talwani and Eldholm, 1977; P. R. Vogt, 1986; P. R. Vogt and Avery, 1974).

Recently, a more complex kinematic model has been suggested for the evolution of the North-East Atlantic (Gaina et al., 2009). Although isolated changes in the plate boundary have been previously proposed, the Gaina et al. (2009) model presented a comprehensive and integrated regional view that attempted to explain and quantify the complexities in the evolution of plate boundaries along the entire North-East Atlantic.

New studies (e.g., Gernigon et al., 2009; Gernigon et al., 2012; and Peron-Pinvidic et al., 2012a; Peron-Pinvidic et al., 2012b) documented the detailed configuration of oceanic floor in the Norway Basin and around and within the Jan Mayen microcontinent. Seafloor spreading history for the last 20 million years has been modelled in detail by using high resolution magnetic data along the Reykjanes, Mohns and Kolbeinsey ridges (Benediktsdóttir et al., 2012; Hey et al., 2010; Ehlers and Jokat, 2009 and Merkouriev and DeMets, 2008).

Chapter 5 presents a new kinematic model that incorporates these latest results into a regional framework.
