2020

General friction and rate and state friction data of powdered fault gouge samples derived from outcrops of the Mai'iu Fault, Papua New Guinae, which is one of the world's most rapidly slipping low-angle normal faults, The experiments show that gouges from the shallowest portion of the fault...

Top-view and cross-section photographs from analogue experiments of strain partitioning around a rigid indenter performed in the Tectonic modelling laboratory (TecLab) at Utrecht University

Nemanja Krstekanić | Ernst Willingshofer

2020

This dataset contains original top-view and cross-section photographs of 12 crustal-scale analogue models. Top-view photographs were taken in regular time intervals from the beginning until the end of each experiment (for details see below). Cross-section photographs were taken at the end of...

Data supplement to: Mapping and classifying large deformation from digital imagery: application to analogue models of lithosphere deformation

Taco Broerse | Nemanja Krstekanic | Ernst Willingshofer

2021

The dataset consists of the original top-view and cross-section digital photographs of the model presented in Broerse et al. (2020) (Mappingand classifying large deformation from digital imagery: application to analogue models of lithosphere deformation.). The top-view images have been taken at...

Mechanical data from rotary shear experiments on material derived from outcrops felsic and mafic rocks in the East African Rift Zone

Nina Hellebrekers

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 equations (see Marone, 1998). We used the rate-and-state friction tool included in the XLOOK program to invert the data for...

Surface DEM’s data and cross-sections from analogue experiments of subduction initiation performed in the Tectonic Laboratory (TecLab) at Utrecht University

Antoine Auzemery | Ernst Willingshofer

2020

In order to show the spatial and temporal evolution of deformation and associated surface topography, we present our results in terms of surface scans and final cross sections. The latter are pictures recorded at the end of the experiment. They are obtained at two-third of their width....

Rock magnetic properties for hemipelagic sediments sampled at Site U1518 of IODP Expedition 375 (depth interval: 250-400 mbsf). Data and file information: ‘hysteresis_parameters_curated.txt’ summarizes composition specific parameters from hysteresis and backfield curves....

Frictional properties of simulated shale-coal fault gouges: Implications for induced seismicity in source rocks below Europe’s largest gas field

Jinfeng Liu | Luuk Bernd Hunfeld | André Rik Niemeijer | Christopher James Spiers

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...

Large-scale biaxial experiments on frictionally heterogeneous faults: Mechanical data and selected strain and image data

Loes Buijze | Yanshuang Guo

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...

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."

Jeroen. F. Van Stappen | Suzanne J.T. Hangx

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 sand deformation has started to use techniques that allow for direct observation of the in-situ grain-scale...

Frictional healing data from direct shear slide-hold-slide experiments performed on simulated fault gouges from the Groningen gas field

Luuk Bernd Hunfeld

2020

We investigated the frictional strength recovery (healing) and subsequent reactivation and slip-weakening behaviour of simulated fault gouges derived from key stratigraphic units in the seismogenic Groningen gas field (N.E. Netherlands). Direct-shear, Slide-Hold-Slide (SHS) experiments were...
