Microstructures of natural shear zones (NERC grant NE/P001548/1)

The dataset contains information on the crystallographic orientation and on the grain size of minerals in the brittle-viscous shear zones. The methodology used to generate it is polarized light...

Direct shear strength testing data on sedimentary gouge samples under high confining pressure

This dataset contains raw experimental direct shear testing data as presented by "Ougier-Simonin, A., Castagna, A., Benson, P. and Walker, R. (2017). Direct shear characterisation of simulated...

Data and codes to demonstrate measurement of shear-wave attenuation anisotropy beneath the Ethiopian Rift

Shear-wave attenuation anisotropy can provide constraints on mantle melt, such as that present beneath the Ethiopian rift. This package contains codes implementing a new methodology to measure such...

Direct-shear experimental data on sedimentary gouge samples under high confining pressure and sliding velocity steps

This dataset contains raw experimental direct shear testing data as presented by "Ougier-Simonin, A., Castagna, A., Walker, R. J., & Benson, P. M. (2018). Frictional and mechanical behavior of...

Spatial and temporal datasets for shear-thinning and Newtonian small-scale analogue dyke experiments

These data consist of spatial and temporal datasets for 7 different small-scale laboratory experiments of fluid-driven fractures, described in the paper The hidden internal flow dynamics of...

Ultrasonic Shear Wave Velocity and Attenuation during methane hydrate formation in water saturated sandstone (NERC Grant NE/J020753/1)

This dataset is of laboratory ultrasonic shear wave measurements during methane hydrate formation in water saturated Berea sandstone using pulse echo method. We formed methane hydrate and took...

Stratified shear flow dynamics: numerical simulations, experimental data, facility design, and processing tools

This collection brings together five interrelated datasets from the University of Hull research program on the turbulent suspension of sediment in stratified shear flows. It includes: numerical...

Experimental direct shear friction dataset for synthetic clay gouges (NERC grant NE/L002469/1)

Friction coefficient and frictional stability (rate & state parameter) data for triaxially compressed direct shear experiments on kaolinite-rich china clay and Mg-montmorillonite fault gouges...

Data (ultrasonic, mechanical) and microstructures of shear failure in Lanhelin granite under upper crustal conditions (NERC Grant NE/M004716/1)

Data has been recorded during triaxial rock deformation experiments where Lanhelin granite samples were subjected to dynamic and half-controlled shear failure. The data consists of mechanical data...

Mechanical data from laboratory shear failure experiments of fluid saturated Westerly granite (NERC Grant NE/S000852/1)

Data recorded during triaxial rock deformation experiments of Westerly granite in the presence of pressurised pore fluids (water). Data consists of mechanical data (load, displacement, confining...

Experimental mechanical data for single crystal shear experiments (NERC grant NE/M000087/1)

Experimental mechanical data for single crystal shear experiments. Grant abstract: In 2011, NERC began a scoping exercise to develop a research programme based around deep Earth controls on the...

Experimental friction data for simulated Nankai Trough gouges sheared under a range of effective normal stress and pore-fluid pressure conditions (NERC Grant NE/S015531/1)

The data are from a suite of friction experiments performed on simulated gouges from the Nankai Trough (Japan). The simulated gouges were prepared by crushing cuttings of Nankai accretionary...

Micromechanics of shear failure in a porous rock: a combined dataset of high-resolution time-resolved 3D x-ray micro-tomography volumes and local 3D strain fields with contemporaneous acoustic emissions and ultrasonic velocity survey waveforms

This dataset shows both the micro-scale mechanisms and acoustic response involved in shear failure of a deforming porous rock. To our knowledge, this is the first such dataset to combine...
