Short summary
The impact of humidity and gas (CO2, N2, CH4) on saliniferous mineral compositions was studied and show dissolution-recrystallization reactions involving halite, sylvite, kieserite, carnallite and kainite. CO2 causes acidification of the aqueous phase which enhances dissolution rate and reaction kinetics. These simulations allow for the evaluation of the interachtion between and host rock and fillings along the walls of storage caverns in salt deposits.
