Schematic diagram of pressure solution accommodating compression/compaction in a clastic rock. Left box shows the situation before compaction. Red arrows indicate areas of maximum stress (= grain contacts). Blue arrows indicate the flow of dissolved species (e.g., Ca2+ and HCO– 3 in case of limestone) in aqueous solution. Right box shows the situation after compaction. In light coloured areas new mineral growth has reduced pore space.Deformed coral limestone showing flattening accommodated both by plastic deformation of the corals and pressure solution along stylolites.
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.
Evidence for pressure solution has been described from sedimentary rocks that have only been affected by compaction. The most common example of this is bedding plane parallel stylolites developed in carbonates.
In a tectonic manner, deformed rocks also show evidence of pressure solution including stylolites at a high angle to bedding.[4] The process is also thought to be an important part of the development of cleavage.
Theoretical modelsedit
A theoretical model was formulated by Rutter, and a recent mathematical analysis was carried out, leading to the so-called Fowler–Yang equations,[5] which can explain the transition behaviour of pressure solution.

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 Schematic diagram of pressure solution accommodating compression compaction in a clastic rock Left box shows the situation before compaction Red arrows indicate areas of maximum stress grain contacts Blue arrows indicate the flow of dissolved species e g Ca2 and HCO 3 in case of limestone in aqueous solution Right box shows the situation after compaction In light coloured areas new mineral growth has reduced pore space Deformed coral limestone showing flattening accommodated both by plastic deformation of the corals and pressure solution along stylolites 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 Contents 1 Occurrence 2 Theoretical models 3 See also 4 ReferencesOccurrence editEvidence for pressure solution has been described from sedimentary rocks that have only been affected by compaction The most common example of this is bedding plane parallel stylolites developed in carbonates In a tectonic manner deformed rocks also show evidence of pressure solution including stylolites at a high angle to bedding 4 The process is also thought to be an important part of the development of cleavage Theoretical models editA theoretical model was formulated by Rutter and a recent mathematical analysis was carried out leading to the so called Fowler Yang equations 5 which can explain the transition behaviour of pressure solution See also editFick s laws of diffusion Fold geology Rock microstructure Stylolite Terzaghi s principleReferences edit Rutter E H 1983 Pressure solution in nature theory and experiment Journal of the Geological Society London 140 5 725 740 Bibcode 1983JGSoc 140 725R doi 10 1144 gsjgs 140 5 0725 S2CID 128543175 Retrieved 24 November 2010 Rutter E H 1976 The kinetics of rock deformation by pressure solution Philosophical Transactions of the Royal Society A 283 1312 203 219 Bibcode 1976RSPTA 283 203R doi 10 1098 rsta 1976 0079 JSTOR 74639 S2CID 109869067 Yang X S 2000 Pressure solution in sedimentary basins effect of temperature gradient Earth Planet Sci Lett 176 2 233 243 arXiv 1003 4970 Bibcode 2000E amp PSL 176 233Y doi 10 1016 s0012 821x 99 00321 0 S2CID 119161222 Railsback L B Andrews L M 1995 Tectonic stylolites in the undeformed Cumberland Plateau of Southern Tennessee Journal of Structural Geology 17 6 911 915 Bibcode 1995JSG 17 911B doi 10 1016 0191 8141 94 00127 L Fowler A C Yang X S 1999 Pressure solution and viscous compaction in sedimentary basins PDF J Geophys Res B104 B6 12898 12997 Bibcode 1999JGR 10412989F CiteSeerX 10 1 1 190 7826 doi 10 1029 1998jb900029 Retrieved 24 November 2010 nbsp This article about structural geology is a stub You can help Wikipedia by expanding it vte Retrieved from https en wikipedia org w index php title Pressure solution amp oldid 1166635567, wikipedia, wiki, book, books, library,
