Late proterozoic stratigraphy of northwestern Canada and its record of earth system evolution

这项研究计划的目的是利用晚元古代（c。1200-540 Ma）的加拿大西北部的地层记录，以重建北美西北缘的构造历史，并解决悬而未决的问题，地球系统的演化导致的中生代Eon。这项跨学科的研究将联合收割机与最先进的地球化学技术和创新的气候地球化学建模相结合，以限制北美西北部从超大陆Rodinia分裂的时间和性质，确定以前相邻的大陆碎片，确定裂谷和相关岩浆活动对全球气候的影响，并校准地球表面环境中重要地球化学变化的时间和克里思。 野外工作将集中在育空地区和西北地区，那里的元古宙圈内和带已成为解决这些具有全球意义的问题的关键地点。我的研究小组每年夏天将花大约4周的时间进行这项实地工作，这将需要直升机运输到山区，否则无法进入。

The aim of this proposed research program is to use the late Proterozoic (c. 1200-540 Ma) stratigraphic record of northwestern Canada to reconstruct the tectonic history of the northwestern margin of North America and address outstanding questions about the evolution of the Earth system leading into the Phanerozoic Eon. This interdisciplinary research will combine rigorous fieldwork with state-of-the-art geochemical techniques and innovative climate-geochemical modeling to constrain the timing and nature of northwestern North America's break-up from the supercontinent Rodinia, identify the formerly adjacent continental fragments, determine the influence of rifting and associated magmatism on global climate, and calibrate the timing and tempo of important biogeochemical changes within Earth's surface environment. The fieldwork will be centered on the Yukon and Northwest territories, where Proterozoic inliers and belts have emerged as key localities for addressing these questions of global significance. My research group will spend about 4 weeks each summer carrying out this field work, which will require helicopter transport to mountainous terrain that is otherwise inaccessible.
