Geometry and Kinematics of Faulting and Dike Intrusion in the Tertiary East Greenland Rifted Margin

9508250 Karson 该项目将对沿大西洋东北支的东格陵兰裂谷边缘进行测绘和古地磁研究，这是一个独特的隆起和暴露的裂谷大陆边缘区域。裂谷边缘的玄武岩熔岩通常在地震反射剖面上成像为一系列向海倾斜的反射器，记录了大陆边缘在向海底扩张过渡期间的渐进沉降和弯曲。地表测绘将记录断层和玄武岩侵入的相互作用，大型峡湾将提供主要结构关键部分的自然横截面。陆上数据将与海上数据相结合，以提供该大陆边缘内部结构和组成的全面视图。丹麦地质调查局正在提供后勤支持。该项目的结果将提供该大陆边缘内部结构和组成的全面视图，并将适用于各种构造体系的其他裂谷边缘。

9508250 Karson This project will conduct mapping and paleomagnetic studies of the East Greenland rifted margin along the northeast branch of the Atlantic Ocean, a uniquely uplifted and exposed area of rifted continental margin. The basaltic lavas of rifted margins are typically imaged on seismic reflection profiles as a series of seaward-dipping reflectors that record a progressive subsidence and flexure of the continental edge during the transition to seafloor spreading. Surface mapping will document the interaction of faulting and basalt intrusion, and the large fjords will afford natural cross sections of key parts of the major structures. The onshore data will be integrated with offshore data to provide a comprehensive view of the internal structure and composition of this continental margin. Logistical support is being provided by the Danish Geological Survey. The results of this project will provide a comprehensive view of the internal structure and composition of this continental margin, and will be applicable to other rifted margins in a variety of tectonic regimes.
