The margins of the southern North Atlantic Ocean host many of the world's most promising frontier regions for oil and gas exploration, with the Newfoundland and Labrador margins showing the most promise and success to date. Understanding how these regions evolved over geological time is crucial for answering fundamental scientific questions about the rifting of continents, for deciphering how our existing resource discoveries were emplaced, and also for identifying future areas with exploration potential. With the benefit of computational advances, geoscientists can now quantitatively take our current Earth models back through time to their origins. Using deformable plate reconstruction software packages (e.g., GPlates), this project will allow the evolution of the southern North Atlantic Ocean to be sped back through time to the supercontinent of Pangaea, with a level of detail never achieved before. In this way, the opening of the oceans and the formation of key sedimentary basins can be studied both spatially and temporally as they develop. The fragmented tectonic plate models of the margins derived in this study will be used to generate the most realistic plate reconstructions to-date. In addition to contributing to our increasing knowledge of tectonic processes and their importance to industry and Canada's resource economy, the researchers trained during this project will be well poised to continue on as academic researchers or to become knowledgeable technical leaders in industry both in Canada and abroad.

北大西洋南部的边缘拥有世界上许多最有前途的石油和天然气勘探边境地区，纽芬兰和拉布拉多的利润率显示出迄今为止最有希望和成功的。了解这些地区在地质时代的发展如何对于回答有关大陆裂变的基本科学问题至关重要。有了计算进步的好处，地球科学家现在可以将我们当前的地球模型恢复到其起源。使用可变形的板块重建软件包（例如Gplates），该项目将使北大西洋南部的演变可以随着时间的流逝而延续到Pangea的超大陆，并且以前从未达到过一个细节。这样，可以随着它们的发展而在空间和时间上研究海洋的开放和关键沉积盆地的形成。本研究中衍生的边缘的碎片构造板模型将用于生成迄今为止最逼真的板块重建。除了为我们对构造过程的不断知识及其对工业和加拿大资源经济的重要性做出贡献外，在该项目期间接受培训的研究人员还将有很好的努力继续担任学术研究人员，或者成为加拿大和国外行业的知识渊博的技术领导者。
