Trace element concentration of minerals in the Morro São João malignites (Serra do Mar, Brazil)

Guarino, Vincenza | Melluso, Leone | Bonazzi, Mattia | Zanetti, Alberto

2026

The Morro São João intrusion is located in the easternmost part of the Serra do Mar province, along the Cabo Frio lineament (Fig. 1) and has an area of approximately 10 km². It is a Late Cretaceous intrusion formed by clinopyroxenites, melagabbros, shonkinites, malignites, nepheline syenites,...

Trace element data obtained from main minerals in Salitre clinopyroxenite and dunite rocks (APIP, Brazil)

Guarino, Vincenza | Melluso, Leone | Bonazzi, Mattia | Zanetti, Alberto

2026

The Salitre intrusion, which is subdivided into Salitre I and Salitre II. It was dated to ~86-82 Ma by Sonoki and Garda (1988). It is part of the Alto Paranaíba Igneous Province (APIP, Fig. 1) in Brazil. The APIP is one of the largest ultrapotassic/carbonatitic/kimberlitic provinces in the...

Crystal Size Distribution Analyses of Isothermal Deformation Experiments

Calagreti, Camilla | Di Fiore, Fabrizio | Vona, Alessandro

2026

In this work we aimed to investigate and quantify the relative importance of dynamic conditions (e.g., stirring in a Concentric Cylinder apparatus) on the crystallization kinetics of basaltic magmas (Stromboli). This was achieved by observing the final textures of the samples, analysing the...

Intercalibration of the intra-laboratory 40Ar/39Ar reference material Drachenfels sanidine

Di Vincenzo, Gianfranco

2026

The dataset contains full 40Ar/39Ar geochronological data completed by multi-collector noble-gas mass spectrometry using the laser total fusion technique on sanidine separated from the Drachenfels trachyte (Drachenfels, Bad Godesberg, Germany). The Drachenfels sanidine represents a useful...

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...

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

Nemanja Krstekanić

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...

Mechanical and permeability data used in: “Posidonia Shale fracture strength, and permeability of both intact and broken cores”

Suzanne Hangx

2026

Shales are an important caprock overlying the majority of reservoirs targeted for geological storage operations as part of the green energy transition. Such operations require a low caprock permeability, and therefore need to avoid the generation or re-activation of fractures in the caprock...

Data repository to "Seismogenic consequences of carbonation in ultramafic fault zones"

Lisa Eberhard

2026

This data repository contains all data used in "Seismogenic consequences of carbonation in ultramafic fault zones" by L. Eberhard et al. Thermodynamic input files, back-scattered electron images, energy-dispersive X-ray maps, experimental data logs (raw and reduced data) and Rate-and-State...

Data for stiff porous olivine veins prolong fluid retention during serpentinite dehydration

Austin Arias

2026

We calculated the poroelastic moduli of porous olivine aggregates produced through the experimental dehydration of serpentinite. Additionally, we simulated the compaction of strong olivine hosted porous anomalies within weaker serpentine matrix to investigate how the strength of the porous...

Data for reactive porosity generation during serpentinite dehydration produces highly permeable olivine vein networks

Austin Arias

2026

We calculated the permeability of porous olivine aggregates produced through the experimental dehydration of serpentinite. The segmented micro-computed tomography results from Eberhard et al., 2025 (DOI: https://doi.org/10.24416/UU01-WW5PS8) were analyzed by taking subvolumes of increasing size...
