Dataset of wehrlitization process: insights from X-ray Micro-CT of Mt. Vulture (southern Italy) mantle xenoliths
Carnevale, Gabriele
2025
The study of textural and chemical characteristics of mafic minerals from mantle xenoliths is essential to investigate the nature of the upper mantle in a continental geodynamic context, melts generation and their effects related to mantle metasomatism. Particular textures in mantle minerals,...
High-Precision Iron Isotopic Analysis of IAEA-B5 basalt and rock Reference Materials
Di Giuseppe, Paolo | Vezzoni, Simone | Iannini Lelarge, Stefano | Rielli, Andrea | Agostini, Samuele | Dini, Andrea
2025
We report the results of high throughput, robust, and sensitive method for the precise analysis of 56Fe/54Fe and 57Fe/54Fe, performed using Multi-Collector-Inductively Coupled Plasma-Mass Spectrometer (MC-ICP-MS), Thermo Scientific Neptune PlusTM. We measured the Fe isotope compositions of...
3D microXCT scans of 1mm pumiceous clasts from Rungwe Pumice eruption deposit (Tanzania)
Cappelli, Lorenzo | Buono, Gianmarco | Pappalardo, Lucia | Fontijn, Karen | Ernst, Gerald G.J. | van Gerve, Thomas | Namur, Olivier | Sielenou, Vanessa N. | Mbede, Evelyne | Edista, Abdallah | Kwelwa, Shimba
2025
The dataset comprises 3D micro XCT scans collected with a ZEISS Xradia Versa 410 at the Istituto Nazionale di Geofisica e Vulcanologia-Osservatorio Vesuviano (Italy). Samples are ash particles within the 0/-0.5 φ (1-1.4 mm) grain size range collected from different stratigraphic horizons (C, F,...
Contact model and numerical modelling results: “Compaction of the Groningen Gas Reservoir Sandstone: Discrete Element Modelling Using Microphysically Based Grain-Scale Interaction Laws”
Mohammad Hadi Mehranpour
2021
Reservoir compaction, surface subsidence and induced seismicity are often associated with prolonged hydrocarbon production. Recent experiments conducted on the Groningen gas field’s Slochteren sandstone reservoir rock, at in-situ conditions, have shown that compaction involves both poro-elastic...
Hydrothermal friction data of samples obtained from outcrops of the Mai'iu Fault, Papua New Guinae
Andre Rik Niemeijer
2020
General friction and rate and state friction data of powdered fault gouge samples derived from outcrops of the Mai'iu Fault, Papua New Guinae, which is one of the world's most rapidly slipping low-angle normal faults, The experiments show that gouges from the shallowest portion of the fault...
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...
A database of analogue models and geophysical data investigating caldera resurgence; DynamiCal project
Sánchez Alvarez, Claudia Paz | Bonini, Marco | Maestrelli, Daniele
2025
In this dataset we provide data for 6 experimental models of caldera collapse and subsequent resurgence monitored through geophysical sensors (a force or “impact sensor”, Piezotronics PCB 104 200B02 and a Triaxial piezoelectric accelerometer, Model 356B18). The analogue modelling experiments...
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...
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....
