Sevier Thrust Belt in SW Utah This is part of the Sevier-Laramide Project, an archive of photos, videos, documents, and maps of outcrops of faults and folds created in the Sevier (Cretaceous period) and Laramide (Paleocene-Eocene periods) orogenies in the western United States. Materials herein may be used freely for classroom, research, and personal use only.

Sevier Thrust Faults in Southern Nevada Thrust faults in southern Nevada formed because of tectonic collisions during the Sevier orogeny (Cretaceous, about 160-60 million years), which shoved continental shelf and margin sedimentary rock layers eastward by at least 50 km.   Watch this video flyover on YouTube by clicking on the picture or the link:  https://youtu.be/tsIOEjypEcQ Wheeler Pass Thrust See in YouTube:   https://www.youtube.com/watch?v=vFzsFXEs6aA This thrust places the early Proterozoic (1.6 to 2.5 billion years) Stirling Quartzite over the much younger Mississippian and Pennsylvanian strata (between 360 and 300 million years).  A close-up view of the thrust in Wheeler Pass. Looking northeast from Wheeler Pass along the fault.  The Stirling Quartzite is the lighter colored rocks above the thrust. Gass Peak Thrust To the east of Wheeler Pass is Gass Peak and its namesake thrust, which are interpreted as correlative. The current Google aerial...
