Characterizing the evolution of porosity and permeability in porous media undergoing pressure solution creep.
… modeled sphere packs. The effects of varying pressure, temperature, and stress upon these properties are evaluated in numerically derived sphere packs undergoing creep and elastic compaction processes. This thesis will utilize the abilities of the lattice Boltzmann method and the network model …

The Role of Water and Strain Rate in the Deformation of Limestone
… presence of water, the extent of intergranular pressure solution increases with increasing confinements. The positive correlation between the extent of intergranular pressure solution and the magnitude of weakening suggests that intergranular pressure solution exerts important controls in …

Nanoscale insight into tribomechanical and hydrothermal process at calcite surface
… in aqueous environment. The induced dissolution and precipitation, commonly described as pressure solution and cementation, actively reconstruct calcite surfaces and are hypothesized to play a decisive role in modulating frictional response in carbonate-rich faults. Yet, the mechanisms …

Depositional environments, ichnology and diagenesis of the upper Frobisher-Alida beds of the Elkhorn Ranch and Roughrider fields of western North Dakota
… replacement, chemical compaction, pressure solution and neomorphism. Multiple dolomitization episodes were due to the movements of magnesium-rich pore fluids released during pressure solution. </p>

Diagenesis of the B chalk, B marl, and Fort Hays member of the Niobrara Formation, Denver Basin, Colorado
… supported by little evidence of compaction or pressure solution, as well as early lithification of the carbonate mud. As a result, the Fort Hays presented more enriched δ18O values than were seen in the chalks and marls. Evidence for early diagenesis was also present in the cathodoluminescence …

Deformation mechanics of quartz at a single asperity under hydrothermal conditions
Pressure solution is a naturally occurring deformation process in fluid-bearing rocks, with implications for sediment consolidation rates and deformation in the mid to upper crust. The process involves dissolution at asperities under load; diffusion along grain-to-grain contacts; and precipitation …

Synthesis, characterization, and biotemplated assembly of indium nitride and indium gallium nitride nanoparticles
A low-temperature, ambient pressure solution synthesis of colloidal InN nanoparticles is presented. This synthesis utilizes a previously dismissed precursor and results in individual, non-aggregated nanoparticles with long-term solubility and stability in organic solvents. These nanoparticles are …

Characterization of Structures and Deformation in the Brittle-Ductile Transition, Western Termination of the Chugach Metamorphic Complex, Southern Alaska
… to be of lesser influence included increased pressure solution caused by high fluid mobility, a lack of pore space, high levels of free aluminum, and a load-bearing framework of phyllosilicates.

Experimental and theoretical studies of reactive transport processes in soluble porous rocks
… processes involve fluid flow and reactions (dissolution, precipitation, and pressure solution) driving the evolution of the rock-fluid systems, which may result in favorable processes such as increased oil production by reservoir acid stimulation, or undesired processes such as caves and …

A New Method for the Rapid Calculation of Finely-Gridded Reservoir Simulation Pressures
… of finely-gridded reservoir simulation pressures has been developed. It is estimated to be as much as hundreds to thousands of times faster than other methods for very large reservoir simulation grids. The method extends the work of Weber et al. Weber demonstrated accuracies for the …

The Fries Fault near Riner, Virginia: an example of a polydeformed, ductile deformation zone
… combined with chemical processes (primarily pressure solution), are the dominant strain-accommodation mechanisms in the formation of S<sub>m</sub>. Rocks within the fault zone have undergone four phases of Paleozoic deformation. An early S₁ foliation has been nearly completely transposed by …

Towards Coupled Nonhydrostatic-Hydrostatic Hybridizable Discontinuous Galerkin Method
… and overturning. Such dynamics require multi-resolution non-hydrostatic (NHS) ocean models. It is known that the main computational cost for NHS models arises from solving a globally coupled elliptic PDE for the NHS pressure. Optimally reducing these costs such that the NHS dynamics are resolved …
