Pressure solution is a phenomena in which solids, immersed in liquids containing components of the solid, have altered solubility when stressed (Yost and Aronson, 1987). It has been identified as a dominate creep mechanism in granular halite (Spiers et al., 1989) and probably represents an important deformation mechanism for halite backfill. Spiers et al. (1989) found that pressure solution governed creep shows a exponential stress dependence of 1 to 2 at low stresses and densities, while grain indentation and precipitation of material in the pores of the backfill are indicative of pressure solution creep.

A direct coupling of mechanics and chemistry arises through pressure solution. Grain dissolution at stressed grain–grain contacts induces compaction and, thereby, contributes to the total rate of strain. The rate of this pressure solution contribution depends on the stress at grain–grain contacts and, hence, on the macro-stress, fluid pressure, and composition and rock texture (Renard et al. 2000).
An alternative to the fault-valve model
Published in Australian Journal of Earth Sciences, 2023
We now turn to the dissolution-deposition process for stressed quartz. The process known as pressure solution consists of dissolution of material at places where the Helmholtz energy arising from strain is high and transfer of that material into a nearby fluid where it may be transported by advection and/or diffusion in the fluid. The thermodynamics of the process was first discussed by Gibbs (1876) and elaborated upon by Cahn (1980, 1989), Kamb (1961) and Sekerka and Cahn (2004).
