Pressure solution
Rock deformation mechanism involving minerals dissolution under mechanical stress
In structural geology and diagenesis, pressure solution or pressure dissolution is a deformation mechanism that involves the dissolution of minerals at grain-to-grain contacts into an aqueous pore fluid in areas of relatively high stress and either deposition in regions of relatively low stress within the same rock or their complete removal from the rock within the fluid. It is an example of diffusive mass transfer.[1]
The detailed kinetics of the process was reviewed by Rutter (1976),[2] and since then such kinetics has been used in many applications[3] in earth sciences.
