Ring-shear test data of feldspar sand from the CNR-IGG Tectonic Modelling Laboratory at the University of Florence (Italy)

Zwaan, Frank | Rudolf, Michael | Pohlenz, Andre | Corti, Giacomo | Keir, Derek | Sani, Federico

2020

This dataset provides internal data from ring-shear tests (RST) on a feldspar sand material that has been used in tectonic experiments by among others Montanari et al. (2017) and Zwaan et al. (2020) in the Tectonic Modelling Laboratory of CNR-IGG at the Earth Sciences Department of the...

Velocity-dependent slip weakening by the combined operation of pressure solution and foliation development

Niemeijer, Andre

2018

Phyllosilicate-bearing faults are characterized by an anastomosing foliation with intervening hard clasts and are believed to be long-term weak structures. Here, I present results of sliding experiments on gouges of 80 wt% quartz and 20 wt% muscovite, sheared under hydrothermal conditions at...

Supplementary material to "Machine Learning can predict the timing and size of analog earthquakes"

Corbi, Fabio | Sandri, Laura | Bedford, Jonathan | Funiciello, Francesca | Brizzi, Silvia | Rosenau, Matthias | Lallemand, Serge

2018

This data set includes the results of digital image correlation of one experiment on subduction megathrust earthquakes with interacting asperities performed at the Laboratory of Experimental Tectonics (LET) Univ. Roma Tre in the framework of AspSync, the Marie Curie project (grant agreement...

Discrete Element Method model data of biaxial shear deformation

van den Ende, Martijn

2018

Owing to their destructive potential, earthquakes receive considerable attention from laboratory studies. In friction experiments, stick-slips are studied as the laboratory equivalent of natural earthquakes, and numerous attempts have been made to simulate stick-slips numerically using the...

4D X-Ray CT data and surface view videos of analogue models exploring rift interaction in orthogonal and rotational extension

Zwaan, Frank | Schreurs, Guido

2020

This data set includes videos depicting the surface evolution of 29 analogue models on crustal extension, as well as 4D CT imagery (figures and videos) of two of these experiments. The experiments examined the influence of the method for driving extension (orthogonal or rotational) on the...

Supplementary material to: A refined age calibrated paleosecular variation and relative paleointensity stack for the NW Barents Sea: implication for geomagnetic field behavior during the Holocene.

Caricchi, Chiara | Sagnotti, Leonardo | Campuzano, Saioa A. | Lucchi, Renata Giulia | Macrì, Patrizia | Rebesco, Michele | Camerlenghi, Angelo

2020

This dataset includes paleomagnetic and rock magnetic analyses from four sediment cores collected on continental slope of Storfjorden and Kveithola trough‐mouth fans (western Spitsbergen margin, southern Svalbard archipelago). In detail, piston core SV-04 was collected during the Spanish...

Compaction creep data uniaxial compaction of quartz sand in various chemical environments

Schimmel, Mariska | Hangx, Suzanne | Spiers, Chris

2019

We studied the effect of pore fluid chemistry on compaction creep in quartz sand aggregates, as an analogue for clean, highly porous, quartz-rich reservoir sands and sandstone. Creep is specifically addressed, because it is not yet well understood and can potentially cause reservoir...

Mechanical and microstructural data used in: “Inelastic deformation of the Slochteren sandstone: Stress-strain relations and implications for induced seismicity in the Groningen gas field"

Pijnenburg, Ronald | Verberne, Berend | Hangx, Suzanne | Spiers, Christopher

2019

Pore pressure reduction in sandstone reservoirs generally leads to small elastic plus inelastic strains. These small strains (0.1 – 1.0% in total) may lead to surface subsidence and induced seismicity. In current geomechanical models, the inelastic component is usually neglected, though its...

Fluid-Induced Fault Slip Experiments in the Laboratory on Critically Stressed Saw-Cut Sandstone Samples with High Permeability

Wang, Lei | Kwiatek, Grzegorz | Rybacki, Erik | Bonnelye, Audrey | Bohnhoff, Marco | Dresen, Georg

2020

To understand the physical mechanisms governing fluid-induced seismicity at field-scale fluid injection projects, we conducted fluid-induced fault slip experiments in the laboratory on critically stressed saw-cut sandstone samples with high permeability using different fluid pressurization...

Experimental and model data of aggregate compaction by pressure solution

van den Ende, Martijn

2017

Intergranular pressure solution creep is an important deformation mechanism in the Earth’s crust. The phenomenon has been frequently studied and several analytical models have been proposed that describe its constitutive behavior. These models require assumptions regarding the geometry of the...
