“…Due to the almost impermeable character of salts, they have been broadly studied for natural gas and petroleum reservoirs as potential seals and hydrocarbon traps (e.g., subsalt traps, Evans et al, 1991;Magri et al, 2008;Urai et al, 2008;Warren, 2016). Moreover, the rheology of halite and other chlorides allows them to migrate from deep to shallower locations, at the time they modify the geothermal gradient due to their high thermal conductivity (i.e., salt-chimney effect, O'Brien and Lerche, 1984 In this context, salt diapirs and walls and their anking sedimentary successions are being proposed for an increasing amount of carbon-neutral and decarbonization purposes, like the emplacement of salt caverns for subsoil hydrogen storage (Lankof and Tarkowski, 2020;Lankof et al, 2022;Muhammed et al, 2022;Allsop et al, 2023) Carbon Capture and Storage (CCS) (Evans and Holloway, 2009), or geothermal energy production (Huenges, 2016;Daniilidis and Herber, 2017;Duffy et al, 2023). Contrary to the non-porous, low permeable, and highly thermal conductive halite, salt-anking sedimentary rocks show signi cant compositional and petrophysical variability depending on factors such as lithology, diagenesis, and fracturing (Sass and Götz, 2012;Moeck, 2014;Rowan et al, 2020a;Mitjanas et al, 2024).…”
