Large-scale biaxial experiments on frictionally heterogeneous faults: Mechanical data and selected strain and image data
Buijze, Loes | Guo, Yanshuang
2020
Frictional heterogeneity within fault zones is one of the factors proposed to explain the spectrum of slow, intermediate, and fast slip behaviors exhibited by faults in nature. Numerical modeling shows how even a simplified model setup incorporating sliding on a velocity-weakening (VW) patch...
Rotary Shear Experiments on Glass Bead Aggregates
Korkolis, Evangelos
2021
Constant sliding velocity (i.e. rate of rotation) friction experiments on mm-thick layers of glass beads, under room temperature and humidity conditions. Stick-slip in sheared granular aggregates is considered to be an analog for the intermittent deformation of the earth’s lithosphere via...
Stress-cycling data uniaxial compaction of quartz sand in various chemical environments
Schimmel, Mariska T.W.
2020
Decarbonisation of the energy system requires new uses of porous subsurface reservoirs, where hot porous reservoirs can be utilised as sustainable sources of heat and electricity, while depleted ones can be employed to temporary store energy or permanently store waste. However, fluid...
Frictional properties of simulated shale-coal fault gouges: Implications for induced seismicity in source rocks below Europe’s largest gas field
Liu, Jinfeng | Hunfeld, Luuk Bernd | Niemeijer, André Rik | Spiers, Christopher James
2019
We report 21 frictional sliding experiments performed on simulated fault gouges prepared from shale-coal mixtures. Our aim was to investigate the effects of local coal seam smearing on the frictional properties and induced seismogenic potential of faults cutting the Upper Carboniferous source...
Multi-scale electron crystal-orientation diffraction of seismically active carbonate fault rocks
Ohl, Markus
2020
We determine the active deformation mechanisms in two active carbonate fault zones in Greece. Detailed slip-system analyses in combination with high-resolution nanostructural investigations show a throughout contribution of crystal plasticity, evident from subgrain-wall misorientations....
Electron Backscatter Diffraction (EBSD) data from metabasaltic fault rocks, Woodlark Rift, Papua New Guinea
Mizera, Marcel
2020
Here we provide compositional and crystallographic orientation data on metabasaltic fault rocks exhumed by the Mai’iu fault in the footwall of the Suckling-Dayman Metamorphic Core Complex, SE Papua New Guinea. The present dataset was collected with a SIGMA-VP field emission gun scanning...
Microscopic and spectroscopic data of pseudotachylytes and wall rocks from the Moncuni ophiolite
Plümper, Oliver
2020
We investigated the microstructures and geochemistry of pseudotachylytes found within the ophiolitic peridotites and gabbros from the Moncuni area (Lanzo Ultramafic Massif, Western Alps). The pseudotachylytes preserve dry glass and pristine microlites. The presence of garnet and the static...
Supporting data set for manuscript "Remediation of annular gas migration along cemented wellbores using reactive mineral fluids: experimental assessment of sodium bicarbonate and sodium silicate-based solutions"
Wolterbeek, Timotheus K.T.
2021
Brief description of the Data: This folder contains data for a study on reactive sealing of microannuli along wellbore casing-cement interfaces. The data set consists of four Microsoft Excel Worksheets, containing volume, flow rate, and pressure data with time for reference and reactive flow...
Top-view and cross-section photographs from analogue experiments of strain partitioning during coeval indentation and back-arc extension performed in the Tectonic modelling laboratory (TecLab) at Utrecht University
Krstekanić, Nemanja
2021
This dataset contains original unaltered top-view and cross-section photographs of 4 crustal-scale analogue models. Top-view photographs were taken at a regular time interval from the beginning until the end of each experiment (for details see below). Cross-section photographs were taken at the...
Microstructural data and microscopic stress measurements of natural mineral-hydration reactions
Plümper, Oliver
2022
We investigated the microstructures of periclase-to-brucite hydration domains within marble from the Adamello contact aureole (Italy). The microstructure preserve high differential stresses within the calcite surrounding the hydration domains of up to 1.5 GPa. Samples were investigated using...
