Sevier orogenic belt in Nevada and Utah

Richard Lee Armstrong
Sevier orogenic belt in Nevada and Utah
Geological Society of America Bulletin (1968) 79 (4): 429-458


Sedimentation in the Cordilleran miogeosyncline in Nevada and Utah continued from before the appearance of Cambrian fossils until it was interrupted and shifted eastward into the area of the Colorado Plateau by an orogeny in the western part of the miogeosyncline during Jurassic time. During Cretaceous time the Sevier orogenic belt developed at the eastern edge of the Cordilleran miogeosyncline and was a major source of sediments in the Rocky Mountain miogeosyncline farther east. Decollement thrusts and a few large folds are characteristic of the Sevier orogenic belt, which was broken up principally by north-trending post-Oligocene normal faults. Widespread Tertiary deposits, notably Oligocene ignimbrites, permit paleogeologic reconstruction of the belt.
