Integrated studies of conjugate rifted continental margins are essential for a better understanding of the fundamental processes responsible for the breakup and separation of lithospheric plates. We propose to study the conjugate volcanic margins off mid-Norway and East Greenland to establish the crustal architecture that provides key constraints for the understanding of the processes and the temporal sequence of events involved in volcanic margin formation and evolution. By using the existing databases and collect new 2D regional deep seismic data off mid-Norway and East Greenland in addition to a detailed 3D survey on the East Greenland margin we will focus on: (1) Crustal and uppermost mantle architecture, (2) tectonic and magnetic interplays and styles prior to, during and subsequent to breakup, (3) regional extension and magmatism, including estimates of volume and rates, (4) alongstrike segmentation, magmatic and tectonic (a)symmetry, structural inheritance, and (5) interplay of sedimentation, magmatism and vertical motion.
