Kinetics of crack-sealing, intergranular pressure solution, and compaction around active faults
TL;DR: In this paper, the porosity decrease by pressure solution processes around an active fault after an earthquake is modeled based on field observations and experimental data, and the authors arrive at plausible rates of fracture sealing that are comparable to the recurrence time for earthquakes.

Compaction-driven fluid flow in viscoelastic rock
TL;DR: In this article, the authors introduce a mathematical formulation applicable to compaction driven flow for the entire range of rheological behaviors realized in the lithosphere and examine three first-order factors that influence the character of fluid flow: (1) thermally activated creep, (2) dependence of bulk viscosity on porosity, and (3) fluid flow in the limit of zero initial connected porosity.

Evolution of permeability in a natural fracture: Significant role of pressure solution
TL;DR: In this article, a mechanistic model is presented to describe closure of a fracture mediated by pressure solution; closure controls permeability reduction and incorporates the serial processes of dissolution at contacting asperities, interfacial diffusion, and precipitation at the free face of fractures.

Compaction creep of quartz sand at 400-600°C: Experimental evidence for dissolution-controlled pressure solution
TL;DR: In this paper, a microphysical model for compaction creep by intergranular pressure solution (IPS) against isostatic hot pressing experiments performed on quartz sand under conditions expected to favor pressure solution was presented.
Journal ArticleDOI
A mechanistic model for compaction of granular aggregates moderated by pressure solution
TL;DR: In this paper, a model for the compaction of granular aggregates that accommodates the serial processes of graincontact dissolution, grain-boundary diffusion, and precipitation at the pore wall is presented.

A Model for Boundary Diffusion Controlled Creep in Polycrystalline Materials
TL;DR: In this article, the authors discussed the mechanism of creep in polycrystalline alumina based on the differences between the lattice and boundary diffusion models and showed that the boundary diffusion model is more stable than lattice diffusion model, while the grain size dependence and the numerical constant are greater.

Diffusion-accommodated flow and superplasticity
M.F. Ashby,R. A. Verrall +1 more
TL;DR: In this article, a new mechanism for superplastic deformation is described and modelled, which differs fundamentally from Nabarro-Herring and Coble creep in a topological sense: grains switch their neighbors and do not elongate significantly.
