Petrologic and Structural Analysis of the Tantato Domain, Saskatchewan: Implications for the Evolution of the North American Craton

雪鸟带是横跨北美从落基山脉到哈德逊海峡的一个主要构造断裂，它标志着拉埃省和赫恩太古代省之间的边界，并可能代表着这些古老省份(微大陆？)是连在一起的。该项目是与加拿大地质调查局合作研究计划的一部分。它将专注于塔纳塔斯地区的变质和构造历史，这是萨斯喀彻温省东北部雪鸟变形带暴露最好的部分之一。该地区糜棱岩的研究结果将有助于约束形成雪鸟带的变形过程中的相对运动和压力-温度条件，从而有助于理解其在北美太古代发展中的意义。

The Snowbird zone is a major structural break crossing North America from the Rocky Mountains to Hudson Strait, it marks the boundary between the Rae and Hearne Archean provinces and may represent the suture along which these ancient provinces (micro- continents?) were attached. This project is part of a collaborative research program with the Geological Survey of Canada. It will focus on the metamorphic and structural history of the tantato domain, one of the best exposed parts of the Snowbird deformation zone, in northeastern Saskatchewan. Results from the study of mylonites in the domain should help constrain the relative motions and pressure-temperature conditions during the deformation that produced the Snowbird zone, and therefore help understand its significance in the Archean development of North America.
