the results were interpreted to support the charleston transverse zone forming during the sevier orogeny to accommodate geometric changes along strike of the thrusts. the zone served as a linking tool of the various segments of the orogeny. the transverse zone varied throughout the region in terms of depth and displacement. the zone was later tilted and was reactivated through crustal extension. results also support the uinta recess forming during the sevier orogeny due to similar geometric crustal accommodation. displacement on sevier aged thrust faults caused the shaping of the curvature of the uinta recess prior to uplift of the uinta/cottonwood arch.
