Large-scale biaxial experiments on frictionally heterogeneous faults: Mechanical data and selected strain and image data

Buijze, Loes | Guo, Yanshuang

2020

Frictional heterogeneity within fault zones is one of the factors proposed to explain the spectrum of slow, intermediate, and fast slip behaviors exhibited by faults in nature. Numerical modeling shows how even a simplified model setup incorporating sliding on a velocity-weakening (VW) patch...

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...

Stress-cycling data uniaxial compaction of quartz sand in various chemical environments

Schimmel, Mariska T.W.

2020

Decarbonisation of the energy system requires new uses of porous subsurface reservoirs, where hot porous reservoirs can be utilised as sustainable sources of heat and electricity, while depleted ones can be employed to temporary store energy or permanently store waste. However, fluid...

Microscopic and spectroscopic data of pseudotachylytes and wall rocks from the Moncuni ophiolite

Plümper, Oliver

2020

We investigated the microstructures and geochemistry of pseudotachylytes found within the ophiolitic peridotites and gabbros from the Moncuni area (Lanzo Ultramafic Massif, Western Alps). The pseudotachylytes preserve dry glass and pristine microlites. The presence of garnet and the static...

Supporting data set for manuscript "Remediation of annular gas migration along cemented wellbores using reactive mineral fluids: experimental assessment of sodium bicarbonate and sodium silicate-based solutions"

Wolterbeek, Timotheus K.T.

2021

Brief description of the Data: This folder contains data for a study on reactive sealing of microannuli along wellbore casing-cement interfaces. The data set consists of four Microsoft Excel Worksheets, containing volume, flow rate, and pressure data with time for reference and reactive flow...

Top-view and cross-section photographs from analogue experiments of strain partitioning during coeval indentation and back-arc extension performed in the Tectonic modelling laboratory (TecLab) at Utrecht University

Krstekanić, Nemanja

2021

This dataset contains original unaltered top-view and cross-section photographs of 4 crustal-scale analogue models. Top-view photographs were taken at a regular time interval from the beginning until the end of each experiment (for details see below). Cross-section photographs were taken at the...

Microstructural data and microscopic stress measurements of natural mineral-hydration reactions

Plümper, Oliver

2022

We investigated the microstructures of periclase-to-brucite hydration domains within marble from the Adamello contact aureole (Italy). The microstructure preserve high differential stresses within the calcite surrounding the hydration domains of up to 1.5 GPa. Samples were investigated using...

Original microstructural data of altered rocks and reconstructions using generative adversarial networks (GANs)

Amiri, Hamed

2022

We image two altered rock samples consisting of a meta-igneous and a serpentinite showing an isolated porous and fracture network, respectively. The rock samples are collected during previous visits to Swartberget, Norway in 2009 and Tønsberg, Norway in 2012. The objective is to employ a...

Microstructural data used in “Drill core from seismically active sandstone gas reservoir yields clues to internal deformation mechanisms”

Verberne, Berend Antonie | Hangx, Suzanne J.T. | Pijnenburg, Ronald P.J. | Hamers, Maartje F. | Drury, Martyn R. | Spiers, Christopher J.

2022

Europe’s largest gas field, the Groningen field (the Netherlands), is widely known for induced subsidence and seismicity caused by gas pressure depletion and associated compaction of the sandstone reservoir. Whether compaction is elastic or partly inelastic, as implied by recent experiments, is...
