中文摘要
该项目利用同位素地球化学来确定魁北克北部Nuvvuagittuq带的基岩的年龄和特征。这些岩石可能有42.8亿年的历史,是地球上最古老的岩石之一。它们有可能提供对地球早期发生的分化过程的洞察-S历史,例如板块构造的开始和确定地球是否有岩浆海洋。更广泛的影响包括对一名同位素地球化学博士后的培训,以及与普通公众和生活在实地的土著因纽特人社区的接触。
英文摘要
This project uses isotope geochemistry to determine the age and characteristics of basement rocks of the Nuvvuagittuq belt in Northern Quebec. These rocks may be up to 4.28 billion years old, making them amongst the oldest on earth. They have the potential to offer insight into processes of differentiation that occurred early in the earth?s history, such as the start of plate tectonics and determining whether the earth had a magma ocean. The broader impacts include training of a postdoctoral fellow in isotope geochemistry, and outreach to the general public and an indigenous Inuit community living in the field area.
