Crustal architecture and evolution of the conjugate volcanic margins off mid-Norway and East Greenland in a total rift context

对共轭裂陷大陆边缘的综合研究对于更好地了解造成岩石圈板块破裂和分离的基本过程是必不可少的。我们建议研究挪威中部和东格陵兰岛的共轭火山边缘，以建立地壳结构，为理解火山边缘形成和演化的过程和事件的时间顺序提供关键约束。通过使用现有的数据库，收集挪威中部和东格陵兰岛新的2D区域深层地震数据，以及在东格陵兰岛边缘进行详细的3D调查，我们将重点关注：(1)地壳和上地幔结构；(2)断裂前、断裂中和断裂后的构造和磁的相互作用和样式；(3)区域伸展和岩浆作用，包括体积和速率的估计；(4)沿程分段、岩浆和构造；(a)对称、构造继承；(5)沉积、岩浆作用和垂直运动的相互作用。

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.
