The Snowbird Tectonic Zone ( STZ ) is a geological structure in the western Canadian Shield which forms a geophysical boundary between the Hearne Craton and the south-west arm of the Rae Craton . It is enigmatic and has been interpreted as a Proterozoic suture or escape structure, or an Archaean suture reactivated during either the Archaean or Palaeoproterozic. It stretches 2,800 km (1,700 mi) from the Canadian Cordillera north-east to Hudson Bay , diagonally crossing Alberta , Saskatchewan , the Northwest Territories , and Nunavut .

12-675: A younger age (1.84–1.78 Ga) can be inferred from convergence across the STZ in Alberta. Berman, Davis & Pehrsson 2007 interpreted it as part of the Hudsonian orogeny , a collisional event in which microcontinents were accreted to Laurentia around 1.85 Ga. Using U-Pb dating , Baldwin et al. 2004 estimated the timing of eclogite facies metamorphism, a process which require transport to mantle depth, to 1.904 Ga. They, nevertheless, concluded that it remains unclear whether
