The Onion Creek Salt Diapir (OCSD) located in the northern Paradox Basin in Utah is a 0.6 km wide X 3.6 km long X 1.6 km tall salt diapir surrounded by variably deformed Paleozoic through Cenozoic strata. The area is a classic area for the study of deformation around salt diapirs. This study uses high-resolution GPS-enabled-tablet and 3D photogrammetric outcrop model-based field mapping, section measuring, thin section petrography, structural restorations, and newly developed 3D modelling workflows to document the styles, timing, nature, and distribution of deformation in strata surrounding the OCSD. Permian Cutler Group sediments on the northern margin of …
