Cretaceous to early Tertiary paleogeography in the hinterland of the Sevier thrust belt, east-central Nevada

Journal Article · · Geology; (USA)
The Cretaceous to early Tertiary hinterland of the Sevier thrust belt in east-central Nevada underwent two periods of sedimentary basin development. The older (Early Cretaceous) episode is characterized by basins that formed coeval with deformation within a belt of contractional structures. Basins were characterized by periods of through-flowing fluvial drainage. The younger (Late Cretaceous to Eocene) episode of basin development was characterized by internally drained alluvial basins that subsequently expanded into more regional lacustrine basins. Basal alluvial detritus indicates that basin inception occurred as a result of rapid development of topographic relief. Synsedimentary tectonism was characterized by horizontal extension due to attainment of equilibrium topography in response to crustal thickening.
