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.

北大西洋南部边缘地区拥有世界上许多最有前景的石油和天然气勘探前沿地区，其中纽芬兰和拉布拉多边缘地区迄今为止表现出最有希望和最成功的地区。了解这些区域在地质时期如何演化对于回答有关大陆裂谷的基本科学问题、破译我们现有的资源发现是如何发现的以及确定未来具有勘探潜力的区域至关重要。借助计算进步的优势，地球科学家现在可以定量地将我们当前的地球模型追溯到时间的起源。使用可变形板块重建软件包（例如 GPlates），该项目将使北大西洋南部的演化过程能够通过时间回到盘古大陆超大陆，其详细程度是前所未有的。通过这种方式，可以在空间和时间上研究海洋的开放和关键沉积盆地的形成。本研究中得出的边缘碎片构造板块模型将用于生成迄今为止最真实的板块重建。除了增加我们对构造过程及其对工业和加拿大资源经济的重要性的了解之外，在该项目中接受培训的研究人员将做好准备继续担任学术研究人员或成为加拿大和国外工业界知识渊博的技术领导者。
