The Origin Of Anomalous Carbonate Units Outcropping At The Salt Sediment Interface Of The Southern End Of Gypsum Valley Salt Wall, Paradox Basin, Colorado, Allison M. Mast
Open Access Theses & Dissertations
Understanding structural, stratigraphic, and petrographic complexities at the salt-sediment interface of diapirs has important implications in accurately assessing hydrocarbon reservoir quality and near-diapir trap geometries, and may aid in more accurate predictions for locating the true margin of salt in diapiric layered evaporites. The southwest margin of the exhumed Gypsum Valley Salt Wall, Paradox Basin, southwest Colorado, provides a rare view of this interface where onlapping and overlapping wedges of Late Permian and Jurassic halokinetic sequences overlie an angular unconformity truncating near-vertical, highly deformed carbonate beds formerly mapped as Pennsylvanian Honaker Trail Formation. This study investigates three possible alternative origins …
