Pressure solution

<p>In <a href="/facts/Structural_geology/e6tGSc6K">structural geology</a> and <a href="/facts/Diagenesis/F1nATwdp">diagenesis</a>, pressure solution or pressure dissolution is a <a href="/facts/Deformation_mechanism/x44TyabP">deformation mechanism</a> that involves the <a href="/facts/Solvation/JVM6j8R1">dissolution</a> of minerals at <a href="/facts/Terzaghi%2527s_principle/EHeTwwqA">grain-to-grain contacts</a> into an <a href="/facts/Aqueous_solution/eRNr3MH2">aqueous</a> <a href="/facts/Porosity/UoyAJU8X">pore</a> fluid in areas of relatively high <a href="/facts/Stress_(physics)/ErAXDbbd">stress</a> 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 <a href="/facts/Molecular_diffusion/lcIz28qY">diffusive</a> <a href="/facts/Mass_transfer/GrHKD4h2">mass transfer</a>.
</p><p>The detailed <a href="/facts/Chemical_kinetics/D8vyX4aE">kinetics</a> of the process was reviewed by Rutter (1976), and since then such kinetics has been used in
many applications in earth sciences.
