Experimental Evidence for reaction-induced weakening of (Carbonated) Serpentinite Fault Gouges
Lisa Eberhard
2024
We analysed the frictional behaviour of antigorite and carbonated antigorite fault gouges in rotary-shear experiments at Utrecht University. Experiments were conducted at temperatures ranging from 400 - 630 °C, effective normal stresses of 100 - 150 MPa under fluid saturated conditions. This...

Data used in "Deep-Learning-Enhanced Electron Microscopy for Earth Material Characterization"
Hans van Melick
2024
Understanding the distribution and characteristics of microstructures is crucial for the stability and effectiveness of subsurface activities. However, achieving statistical representativeness typically demands imaging a large number of samples at high magnification. To address this, we...
Model output for the paper "Unravelling Processes and Rheology of the Tohoku Earthquake Cycle Using Bayesian Inference"
Celine Marsman
2024
This dataset contains the input and output files of the 2D model data assimilation experiments for interseismic and postseismic deformation associated with the 2011 Tohoku-Oki earthquake. All methods, results, bibliography/citations, and figures are described in detail in the publication:...
Data package on the impact of nanoconfinement on the chemistry of geofluids
Alireza Chogani
2024
To determine the effect of nanoconfinement on the geochemistry of water, we incorporate dielectric permittivity data of nanoconfined water into thermodynamic equilibrium models. We explored water self-ionization, ion pairing, pH, and aqueous speciation under nanoconfinement within the Earth....
Micro Computational Tomography, Acoustic Emission and rock temperature data from frost weathering tests on Dachstein Limestone
Daniel Draebing
2024
We tested the efficacy of frequent diurnal freeze-thaw cycles (FT-1) and sustained freezing cycles (FT-2) on low-porosity Dachstein limestone (0.1 % porosity). For FT-1, we exposed three rock samples with different saturation regimes (30%, 70%, 100%) to 20 freeze-thaw cycles between 10 and...
Unravelling Potential Reaction Intermediates during Catalytic Pyrolysis of Polypropylene with Microscopy and Spectroscopy
Ina Vollmer
2023
While plastics-to-plastics recycling via melting and re-extrusion is often the preferred option due to a relatively low CO2 footprint, this technique requires a highly sorted waste stream and plastic properties can often not be maintained. Obtaining aromatics, such as benzene, toluene, and...
Micro-computed tomography data of solute transport in a saturated and unsaturated sintered glass and Bentheimer sandstone sample
Stefanie Van Offenwert | Veerle Cnudde | Sharon Ellman | Tom Bultreys
2024
This dataset was used in the study of Van Offenwert et al. (2024). It contains time-resolved laboratory-based micro-CT images of saturated and unsaturated solute injection experiments in sintered glass and Bentheimer sandstone. Based on the grey values in the resolved pore space, pore-scale...
Molecular simulation data package on the dielectric permittivity of nanoconfined geofluids with various salt concentrations
Alireza Chogani
2024
To determine the effect of salinity on the dielectric permittivity of nanoconfined geofluids, we employed molecular dynamics (MD) simulations of saline water confined in calcite slit nanochannels. This data package includes data points, figures, and MD input files to simulate the behaviour of...
Catalytic Pyrolysis of Polyethylene with Microporous and Mesoporous Materials: Assessing Performance and Mechanistic Study
Jochem van de Minkelis
2024
This data package underlies the results published in 'Catalytic Pyrolysis of Polyethylene with Microporous and Mesoporous Materials: Assessing Performance and Mechanistic Study' by Johan H. van de Minkelis. The experimental section in the supporting information gives an detailed explanation how...
