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.

共轭裂痕大陆边缘的综合研究对于更好地理解负责破裂和分离岩石圈板的基本过程至关重要。我们建议研究中间和东格陵兰岛的共轭火山缘，以建立地壳结构，为理解过程和涉及火山缘形成和进化的事件的时间顺序提供了关键的限制。通过使用现有数据库并收集新的2D区域深层地震数据，除了对东格陵兰边缘的详细3D调查外，我们还将重点介绍：（1）地壳和最上面的地幔结构，（2）tectonic and gromplays and grouity and tocemitions in of Brockiention soprigity insimal and（3）区域性和元素（3）区域性，（3）区域性，（3）区域性，（3）区域性，（3）区域性（3），（3）的速度（3）与分割，岩浆和构造（a）对称性，结构遗传以及（5）沉积，岩浆和垂直运动的相互作用。
