The Sask craton is a large, ancient geological structure located in the western part of the Trans-Hudson Orogen in Canada. It is made up of Precambrian rock formations that are more than 2 billion years old and is considered to be a stable part of the Earth's crust. The craton is bounded by the Hearne Province margin, which is characterized by deformation and metamorphism caused by the collision of tectonic plates. Seismic reflection studies have been used to study the structure and evolution of the Sask craton and Hearne Province margin."The Sask Craton and Hearne Province margin: Seismic reflection studies in the western Trans-Hudson Orogen". {{cite journal}}: Cite journal requires |journal= (help)
