, split from the continent of Rodinia roughly 750 million years ago to form the geologic core of North America. However, the mountain-building or orogeny of the Torngats took place much more recently, and is characteristic of the folding and faulting that defines the series of geological events known as Arctic Cordillera. This, according to some, makes the Torngats, as mountains, "distinct compared to the surrounding Precambrian Canadian Shield," though they are ultimately composed of shield rock. Evidence of this dramatic cordilleran folding and faulting characterizing the Torngat Mountains can be seen distinctly in rocks where the North American Craton long ago collided with the Nain Craton, later exposed in cross-section by glacial scouring, especially at Saglek Fjord.


Glaciation

The ranges of the Torngat Mountains are separated by deep

In popular culture

In the CBC Series ''Geological Journey'' the Torngat mountains are feature

Notably, a billion-year-old coal seam (based on algae, not peat swamps) was discovered in the Torngat mountains on the Newfoundland Coast as part of the filming of the series. ''Backcountry Magazine'' ran a feature story written by Drew Pogge in 2009 on steep skiing in the Torngat Mountains, notably first descents in Nachvak and Saglek fjords, as well as on the Caubvick massif.
