Friction and compaction data of simulated fault gouges derived from the Basal Zechstein caprock of the Groningen gas field
Hunfeld, Luuk Bernd; (2019)
We investigated the rate-and-state frictional properties of simulated anhydrite-carbonate fault gouge derived from the Basal Zechstein caprock overlying the seismogenic... -
Large-scale biaxial experiments on gypsum-gouge faults and a bare PMMA fault: Mechanical data and selected strain and image data
Buijze, Loes; (2019)
Geodetic observations and large-scale laboratory experiments show that seismic instability is preceded by slow slip within a finite nucleation zone. In laboratory experiments... -
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... -
Micro-XCT images, grain size distributions and mechanical data used in: "Uniaxial compaction of sand using 4D X-ray tomography: The effect of mineralogy on grain-scale compaction mechanisms."
Van Stappen, Jeroen. F.; Hangx, Suzanne J.T.; (2020)
The mechanical behaviour of sand aggregates is often studied as a proxy for poorly consolidated sands and highly porous sandstones. Only recently research aimed at understanding... -
Mechanical data from rotary shear experiments on material derived from outcrops felsic and mafic rocks in the East African Rift Zone
Hellebrekers, Nina; (2019)
In all experiments, multiple series of velocity-steps were performed to obtain the velocity dependence of friction. The data can be modeled using rate-and-state friction... -
Intergranular clay films control inelastic deformation in the Groningen gas reservoir: Evidence from split-cylinder deformation tests
Pijnenburg, Ronald; Verberne, Berend Antonie; Hangx, Suzanne; Spiers, Christopher James; (2019)
Production of oil and gas from sandstone reservoirs leads to small elastic and inelastic strains in the reservoir, which may induce surface subsidence and seismicity. While the... -
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...
