Thelon orogenic belt

The Thelon orogenic belt is a geological feature formed by the collision of continental fragments in North America approximately 1.97 billion years ago. This collision occurred between the Slave province and the western Churchill province, resulting in the formation of this orogenic belt, which extends from central Alberta to the northwestern part of Greenland.1

Orogenic belts are mountain-building regions, and the Thelon orogenic belt is a product of Precambrian tectonic activity. This period saw the amalgamation of continental crust, leading to the formation of stable landmasses like the Canadian Shield. The structure and formation of such belts are complex, often involving thrusting and folding of rock layers. They can be compared to modern tectonic collages found in areas like the Pacific Ocean.12
