“…1A), excellent outcrop exposures and an abundance of subsurface data have facilitated the reinterpretation of stratal geometries and structures adjacent to the salt walls, sparking renewed interest in understanding the salt tectonic and stratigraphic history of the basin (Lawton and Buck, 2006;Trudgill, 2011;Banham and Mountney, 2013;Venus et al, 2015;Rowan et al, 2016;Hartley and Evenstar, 2017;Escosa et al, 2018). For example, the stratal architecture adjacent to salt walls in the northwestern part of the Paradox Basin, including the Salt Valley, Castle Valley, and Moab Valley salt walls, has revealed patterns of fluvial-alluvial deposition in response to salt movement during the Permian through Triassic (Matthews et al, 2007;Mountney, 2013, 2014;Venus et al, 2015;Hartley and Evenstar, 2017) and the identification of steeply dipping strata adjacent to the salt walls (Trudgill, 2011) that are now interpreted as megaflaps (i.e., Giles and Rowan, 2012). Moreover, new mapping and reinterpretation of stratal geometries along the Gypsum Valley and Castle Valley salt walls has identified a number of newly recognized and reinterpreted halokinetic and near-diapir features, including megaflaps, counterregional faults, salt shoulders, radial faults, secondary welds, and lateral caprock (Fig.…”
