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...

Magnetic biomonitoring of airborne metallic particles using lichen transplants on cultural heritage – The Jerónimos Monastery, Lisbon, Portugal. Preliminary Results

Moreira, Mário | Rocha, Bernardo | Pinho, Pedro | Spagnuolo, Lilla | Donas Botto, Margarida | Winkler, Aldo

2026

Magnetic biomonitoring employing lichens transplants is a non-invasive and low-cost method to evaluate airborne particulate matter (PM) pollution originated from urban traffic. This study was designed to assess the indoor deposition of traffic-related PM within the 16th-century Jerónimos...

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...

Digital image correlation data of analogue models of strike-slip fault evolution in quartz sand G12

Elston, Hanna | Kosari, Ehsan | Cooke, Michele | Rosenau, Matthias

2026

The data set includes the 3D incremental displacement fields resulting from Digital Image Correlation (DIC) analysis of four strike-slip experiments performed at the laboratory for experimental tectonics at GFZ Helmholtz Centre for Geosciences in Potsdam in 2022. The data here include the...

Data from seismic slip-pulse experiments simulating induced earthquake rupture in the Groningen gas field

Luuk Bernd Hunfeld

2021

Rock materials show dramatic dynamic weakening in large-displacement (m), high-velocity (~1 m/s) friction experiments, providing a mechanism for the generation of large, natural earthquakes. However, whether such weakening occurs during induced M3-4 earthquakes (dm displacements) is unknown. We...

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, IODP Site U1518, depth interval 250-400 mbsf

Annika Greve

2021

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 slip weakening and shear-enhanced crystallinity in simulated coal fault gouges at subseismic slip rates

Jinfeng Liu | Luuk Bernd Hunfeld

2020

We report seven velocity stepping (VS) and one slide-hold-slide (SHS) friction experiments performed on simulated fault gouges prepared from bituminous coal, collected from the upper Silesian Basin of Poland. These experiments were performed at 25-45 MPa effective normal stress and 100 ℃,...

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...

Friction and compaction data of simulated fault gouges derived from the Basal Zechstein caprock of the Groningen gas field

Luuk Bernd Hunfeld

2019

We investigated the rate-and-state frictional properties of simulated anhydrite-carbonate fault gouge derived from the Basal Zechstein caprock overlying the seismogenic Groningen gas reservoir in the NE Netherlands. Direct shear experiments were performed at in-situ conditions of 50-150 °C...
