Micro-computed tomography data of solute transport in a saturated and unsaturated sintered glass and Bentheimer sandstone sample
Van Offenwert, Stefanie | Cnudde, Veerle | Ellman, Sharon | Bultreys, Tom
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
Chogani, Alireza
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...
Mineralogical characterization data of Fe oxides during interaction with fluid Li at various pH
Zhang, Xu
2024
Mineralogical characterization (XRD, FTIR, and Raman spectroscopy) of oxides including poorly crystallized goethite (GX), well crystallized goethtie (GN), synthesized hematite (HX), commercially available hematite (HN), wustite (W), and magnetite (M). The measurements were made before and after...
Micro Computational Tomography, Acoustic Emission and rock temperature data from frost weathering tests on Dachstein Limestone
Draebing, Daniel
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...
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
Chogani, Alireza
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)...
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
Krstekanić, Nemanja
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...
New 2D-to-3D Reconstruction of Heterogenous Porous Media via Deep Generative Adversarial Networks (GANs)
Vogel, Hannah | Amiri, Hamed
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...

µCT data for "A new method for determining fluid flux at high pressures applied to the dehydration of serpentinites"
Eberhard, Lisa
2022
Dehydration of serpentine within a subduction zone setting causes the formation of pore space. The porosity and connectivity of the pores is important for fluid flux through these rocks. The pore space preserved within two recovered high-pressure and high-temperature multi-anvil samples was...
Rotary Shear Experiments on Glass Bead Aggregates
Korkolis, Evangelos
2021
Constant sliding velocity (i.e. rate of rotation) friction experiments on mm-thick layers of glass beads, under room temperature and humidity conditions. Stick-slip in sheared granular aggregates is considered to be an analog for the intermittent deformation of the earth’s lithosphere via...
