摘要：

Experiments in microcapillary tubes have been developed to mimic the effect of dry CO2 onto hydrated minerals such as gypsum. It is concluded that gypsum-bassanite-anhydrite transformations are controlled by the state of the fluid phase. For samples of gypsum heated in vacuum, gypsum-bassanite transition occurs by pseudomorph substitution at 120 degrees C. For samples of gypsum in aqueous medium, the gypsum-bassanite transition starts at 135 degrees C and then the bassanite-anhydrite transition occurs by dissolution / recrystallization at 220 degrees C. There is a strong CO2 effect that facilitates the dehydration of gypsum. In the presence of dry CO2, gypsum-bassanite transition is instantaneous at 31 degrees C. In aqueous media saturated with CO2, gypsum - anhydrite transition appears at 125 degrees C. These experimental results are in full agreement with the conclusions of thermodynamic simulations.
