Upheaval Previous HitDomeNext Hit, a Possible Previous HitSaltNext Hit Previous HitDomeNext Hit in the Paradox Basin, Utah

Richard B. Mattox

Abstract

Upheaval Previous HitDomeNext Hit is a breached domal structure that is surrounded by a well-developed rim syncline; it lies in the rugged canyonlands of southern Utah, near the western margin of the Paradox Basin. Strata that range in age from Permian to Jurassic are exposed in the Previous HitdomeNext Hit and all have been deformed by the forces which produced the feature; about 3000 feet of Pennsylvanian Previous HitsaltNext Hit beds underlies the area of the Previous HitdomeNext Hit. The origin of Upheaval Previous HitDomeNext Hit has not been established, but the following hypotheses have been advanced: (1) it is a cryptovolcanic feature; (2) it is a simple Previous HitsaltNext Hit Previous HitdomeNext Hit; (3) it was formed by meteorite impact; (4) unloading of overburden through stream erosion resulted in the upward migration of the Previous HitsaltNext Hit; and (5) it is a Previous HitsaltNext Hit Previous HitdomeNext Hit produced by multiple Previous HitsaltNext Hit movements resulting from local diastrophism and igneous intrusion. The author suggests that the Previous HitdomeNext Hit is the product of Previous HitsaltTop flowage resulting from differential pressures which were produced by differential compaction of the sediments over and on the flanks of a buried hill, or monadnock, on the Precambrian basement complex.
