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...

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....

Analogue experiments of asthenospheric flow and asthenosphere-lithosphere interaction driving back-arc extension performed in the Tectonic modelling laboratory (TecLab) at Utrecht University: top-view photographs and CT scan images

Nemanja Krstekanić

2024

The present dataset contains data obtained from 10 lithosphere to asthenosphere-scale analogue modelling experiments. These models were built to develop, test and validate a novel analogue modelling approach in which lithospheric deformation is controlled by gravity-driven asthenospheric...

Small-angle neutron scattering, electron microscopy, and molecular simulation data package of nanoporosity in lithospheric rocks and its impact on water permittivity and mineral solubility

Alireza Chogani

2024

We show nanoporosity in a diverse range of lithospheric rocks and determine the impact of nanoconfinement on water permittivity and mineral solubility within the Earth’s lithosphere. This data package includes small-angle neutron scattering (SANS) data and transmission electron microscopy (TEM)...

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...

New 2D-to-3D Reconstruction of Heterogenous Porous Media via Deep Generative Adversarial Networks (GANs)

Hannah Vogel | Hamed Amiri

2024

We imaged samples of Berea sandstone from Ohio (USA) using two 2D imaging techniques, backscattered electron (BSE) and optical microscopy, as well as one 3D imaging technique, X-ray (micro-)computed tomography (XCT). The goal is to employ a deep-learning-based generative model called a...

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...
