Sevier orogeny - Wikipedia
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.

The next orogeny to occur in western North America was the Sevier orogeny. While terranes still played a factor in the deformation, the Sevier orogeny occurred much further inland and was more widespread than the Nevadan orogeny.
Sevier orogeny | Mountain Building, Plate Tectonics
Sevier orogeny, a mountain-building event that produced the Sevier Orogenic Belt, a linear zone of deformed rock strata in the western United States extending from southeastern California northeastward through southern Nevada and western Utah to western Wyoming.

Almost unknown by the general public the Sevier Orogeny is named for the Sevier River of west-central Utah between Zion and Bryce Canyon National Parks. Unlike the Laramide Orogeny that came next and built the Rocky Mountains, the Sevier included two types of mountains.
Sevier Orogeny!: The Cordilleran Thrust System - University of …
The Sevier Orogeny is characterized by thin-skinned deformation where only the upper crust consisting of Proterozoic to Mesozoic sequences and formations accomodates horizontal compression from a convergent plate boundary zone.
Sevier-Laramide fold-thrust belt - Idaho State University
The fold and thrust belt of the Cretaceous Sevier-Laramide orogenic belt spans nearly the entire length of North America, from Alaska to Mexico. It is a fundamental component of the North American Cordillera.

2015年5月18日 · The process that created this stacking up and eastward pushing of thrust-fault slabs is called the Sevier orogeny, named after the Sevier River in Utah. The Sevier orogeny overlaps in time and space with the Laramide orogeny (see next section).
34.1: Western Mesozoic Orogenies - Geosciences LibreTexts
2024年4月11日 · The Sevier orogeny was an Andean-style subduction zone complete with back-arc thrust sheets. As subduction continued, the bouncy of the subducting plate caused the plate to descend at a shallow angle, causing a much-different Laramide orogeny.
Structural geology – Historical Geology
The mountains of Glacier formed during the late Mesozoic and early Cenozoic due to the Sevier Orogeny. This episode of mountain-building shoved older Belt rocks and Mississippian carbonates atop Cretaceous siliciclastic strata in an impressive inversion of their original stratigraphic order.
Sevier Orogeny - WESTERN CORDILLERA
2006年9月12日 · Sevier Orogeny. In western Utah, large-scale older-over-younger thrusting and folding occurred along the northeast-trending Sevier orogenic belt (Armstrong, 1968a). Sevier deformation has been described primarily in western Utah and was extended by various early workers into the eastern and southern portions of Nevada.
