项目摘要

This proposed interdisciplinary research program involves studying the late Proterozoic (1000-540 Ma) geological record of the Yukon. These rocks are exposed in a series of mountainous inliers extending from the Alaska border to the Mackenzie Mountains in the Northwest Territories. The exceptionally preserved stratigraphy in this region records the tectonic evolution of ancestral North America spanning supercontinental break-up. Formerly contiguous sedimentary sequences should be found on the margins of the continental fragments that rifted apart from northern and western Canada from about 850 to 550 million years ago. Together, these rocks bear witness to multiple glacial epochs, at least two of which were global in extent, and to a tumultuous transition to a fully oxygenated environment that supported the origin and diversification of animal life. The complex evolution of the Neoproterozoic Earth system reflects interconnetions between tectonics, global climate, the biosphere, and ocean chemistry. My research group will combine rigorous fieldwork in the Yukon with state-of-the-art geochemical techniques and innovative coupled climate-biogeochemical modeling to establish and interpret the 1) the timing and nature of northwestern North America's break-up from the supercontinent Rodinia, 2) the influence of rifting and associated magmatism on climate and marine geochemistry, and 3) the tempo of important biogeochemical and biospheric changes and their connections to other global events. The research will involve a team of three current McGill PhD students, undergraduate students, and a network of international collaborators. The outcomes will directly assist exploration for sediment-hosted Cu and Fe in northwestern Canada and possible links to mineralized belts on formerly contiguous continents.
这一拟议的跨学科研究方案涉及研究育空地区的晚元古代(1000-540 Ma)地质记录。这些岩石暴露在一系列从阿拉斯加边境延伸到西北地区麦肯齐山脉的山区内层中。这一地区保存异常完好的地层记录了古北美大陆跨越超大陆裂解的构造演化过程。在加拿大北方和西部从大约8.5亿年到5.5亿年前分裂开来的大陆碎片的边缘应该可以找到以前连续的沉积序列。这些岩石共同见证了多个冰川时代,其中至少有两个是全球性的,以及一个动荡的过渡到一个充分氧化的环境,支持动物生命的起源和多样化。新元古代地球系统的复杂演化反映了构造、全球气候、生物圈和海洋化学之间的相互联系。我的研究小组将把联合收割机在育空地区的严格实地考察与最先进的地球化学技术和创新的气候-地球化学耦合模型相结合,以建立和解释1)北美西北部从超大陆Rodinia分裂的时间和性质,2)裂谷和相关岩浆活动对气候和海洋地球化学的影响,(3)重要地球化学和生物圈变化的克里思及其与其他全球事件的联系。该研究将涉及一个由三名麦吉尔大学博士生,本科生和国际合作者网络组成的团队。这些成果将直接有助于勘探加拿大西北部沉积物中的铜和铁,以及与以前相邻大陆上矿化带的可能联系。
