In much of the area, Mississippian, Pennsylvanian, and Permian rocks form long dip-slopes toward the south. Typical of Uinta Mountain structure and representative of the smaller folds...

... of continental growth and the creation of continental fabric. Precambrian sutures, in particular, record continental formation and growth when processes may have differed from those occurring more recently. Starting ca. 1.8 Ga, most of the southwestern United States formed by Proterozoic accretion of active arcs...

... is hypothesized to have formed as a result of thrust faulting along with significant internal block deformation; however, the exact fault kinematics, that is, planar or listric, and the relationship between the uplift of the Palmer Canyon block and the formation of the Cheyenne belt is largely unconstrained...

... trend and geometry. Located north in Lodore Canyon and on strike with the Mitten Park fault, the Disaster fault displaces the Uinta Mountain Group but not the overlying Cambrian Lodore Formation. These fault relationships indicate a pre-Upper Cambrian origin for the Mitten Park/Disaster fault trend...

...Norman C. Williams ABSTRACT Geologic mapping in the South Fork Basin of the western Uinta Mountains, Utah, has yielded data which permit a more accurate interpretation of the position of the pre-Cambrian-Paleozoic contact. Two formations (Ophir and Pine Valley) heretofore assigned to the Cambrian...

... that remain, much is known about the canyon’s development and formation, resulting from more than 150 years of scientific research ( Karlstrom et al., 2012 ). Numerous workers have sought to understand the origin of the Grand Canyon, and one of the basic underpinnings of this understanding is that the canyon...

..., and the deformation mechanisms associated with their formation. Typical profiles of basement-involved structures feature a long, low-dipping (0–20°) backlimb and a relatively short, gently to steeply dipping (30° to overturned) forelimb. The backlimbs of the structures are well imaged on seismic profiles, whereas...

These are overlain on the flanks by thin sediments of unknown age, the Lodore formation. Ordovician rocks were reported by Weed on the south flank. On the other three flanks, however, the oldest...
