At temper atures of 100-200°C, liquid water may exist at negative pressures of up to 100-150 MPa. Owing to an increase in surface tension, the effect is even more significant in salt solutions and occurs at higher tempera tures. A decrease in the linear dimension of fluid phase by an order of magnitude and, correspondingly, a three orders of magnitude decrease in volume (which is proportional to R3) increase the maximum tension by ~25MPa. Tension in the liquid phase of water-salt systems may be higher than ~200 MPa without cavitation. Metastability of water and salt solutions in small sized vacuoles generates stresses in the fluid-mineral system resulting in high solubilities of solid phases. An increase in volume due to coalescence of small inclusions or vanishing of metastability results in an abrupt decrease in supersaturation. %G English %2 https://insu.hal.science/insu-01018693/document %2 https://insu.hal.science/insu-01018693/file/PETR418.pdf %L insu-01018693 %U https://insu.hal.science/insu-01018693 %~ OBSPM %~ SDE %~ INSU %~ BRGM %~ CNRS %~ UNIV-ORLEANS %~ ISTO %~ OSUC %~ GIP-BE %~ VOLTAIRE %~ PSL %~ OBSPM-PSL
