The Sevier orogeny was a mountain-building event that affected western North America from northern Canada to the north to Mexico to the south.
The Sevier orogeny was the result of convergent boundary tectonic activity, and deformation occurred from approximately 160 million years (Ma) ago[2] to around 50 Ma.[3] This orogeny was caused by the subduction of the oceanic Farallon Plate underneath the continental North American Plate. Crustal thickening that led to mountain building was caused by a combination of compressive forces and conductive heating initiated by subduction, which led to deformation.[4] The Sevier River area of central Utah is the namesake of this event.
