Early Magmatic Evolution of the East Greenland Volcanic Rifted Margin

9706677古新世晚期-始新世早期，北大西洋地区的盘古大陆的Lesher分裂与广泛的火山活动和北大西洋大火成岩省（NA-LIP）的形成有关。 该项目的目的是建立高分辨率的岩石学和地球化学地层的陆上部分暴露的火山区沿着东格陵兰中部的塞维尔海岸。 新的成分地层学将跨越NA-LIP的大陆裂谷和海底扩张的开始时期。 本研究结果将为地幔柱引发的大陆裂解和大陆向海洋过渡的地壳结构模型提供约束，并将增加我们对岩浆成因，地壳演化以及火山和构造活动之间的相互作用在LIPs的侵位过程中的理解。 在这项研究中采用的方法包括光学和电子显微镜，X射线荧光光谱法，电感耦合等离子体质谱法，和固体源质谱法。

9706677 Lesher Breakup of the supercontinent Pangaea in the North Atlantic region during late Paleocene-early Eocene time was associated with widespread volcanism and formation of the North Atlantic Large Igneous Province (NA-LIP). The aim of this project is to establish a high resolution petrographic and geochemical stratigraphy of subaerial portions of this volcanic province exposed along the Blosseville Coast of central East Greenland. The new compositional stratigraphy will span the period of continental rifting and the start of seafloor spreading in the NA-LIP. The results of this study will provide constraints for models of plume-initiated continental breakup and crustal architecture of the continent to ocean transition, and will increase our understanding of magma genesis, crustal evolution and the interplay between volcanic and tectonic activity during the emplacement of LIPs. Methods to be employed in this study include optical and electron microscopy, X-ray fluorescence spectrometry, inductively coupled plasma mass spectrometry, and solid-source mass spectrometry.
