- The Sevier orogeny was a time of active horizontal shortening and vertical thickening of the crust, which took place between 165 million and 80 million years ago during the Jurassic and Cretaceous periods123. It produced a zone of eastward-directed thrust faults and folds that represent 40 to 65 kilometres (25 to 40 miles) of crustal shortening in response to compressional forces2. The thrust faults carried their respective thrust sheets up to 50 miles of displacement and the large folds have amplitudes of 5,000 to 10,000 feet1. Similar styles and ages of thrust faults also occur in the Rocky Mountains of Montana, Canada, and Alaska4.Learn more:✕This summary was generated using AI based on multiple online sources.

Today Sevier faults at the surface have been broken up and tilted steeply from their original gently dipping positions due to the extension of the Basin and Range faulting. The earliest thrusts of the Sevier are located furthest west with each newer thrust cutting the older thrust. See more
