Petrological, geochemical and isotopic characterization of kamafugites from East-Central Africa, Italy and Brazil: a review

Innocenzi, Francesca | Foley, Stephen | Ronca, Sara | Agostini, Samuele | Guarino, Vincenza | Lustrino, Michele

2025

Kamafugites are 'exotic igneous rocks' with mineralogical and chemical compositions that differ from those observed in common magmas. Despite their importance, kamafugites are still a poorly constrained topic and they lack a general petrological model due to their variable petrographic,...

Horizontal-to-Vertical Spectral Ratios (HVSR) of NW Italy seismic stations elaborated during the "FOCUS-HVNEA" NOA-ILGE project

Tarchini, Gabriele | Vassallo, Maurizio | Riccio, Gaetano

2026

This data set consists of Horizontal-to-Vertical Spectral Ratios (HVSR) resulting from the application of the software package HVNEA (HV Noise and Earthquake Automatic Analysis) with the aim of comparing them with those resulting from the application of another method, namely STATION (Seismic...

Cathodoluminescence zoning images of Lower El Cajete quartz and sanidine crystals, Valles Caldera, New Mexico, USA

Kim, Jisoo | Roggensack, Kurt | Clarke, Amanda | Costa, Simone | D'Oriano, Claudia

2025

The Valles Caldera, New Mexico, USA was created by two caldera-forming eruptions at ~1.6 and ~1.1 Myr. Since then, post-caldera activity has consisted of lava domes, lava flows, large explosive phases, and a hydrothermal system active today. Possibly the youngest eruption sequence, El Cajete,...

Ring-shear test data of quartz sand SIBELCO S80 used for analogue modelling in the Tectonic Laboratory (TecLab) at Utrecht University

Willingshofer, Ernst | Rosenau, Matthias

2025

This dataset provides friction data from ring-shear tests on quartz sand SIBELCO S80 used in analogue modelling of tectonic processes as a rock analogue for the earth’s upper crust (e.g., Klinkmüller et al., 2016). According to our analysis the material shows a Mohr-Coulomb behaviour...

Apatite fission-track data from the watershed area of the Northern Apennines (Italy)

Balestrieri, Maria Laura | Bonini, Marco | Maestrelli, Daniele | Montanari, Domenico | Sani, Federico

2024

The data-set contains nine apatite fission-track data from samples collected at strategic locations to constrain the age of deformation along an ideal transect crossing the main Apennine watershed (from the north-eastern margin of the Casentino Basin to the Romagna Apennines. Apatite...

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,...

4D X-ray microtomography dataset of well rocks from the Campi Flegrei caldera (4dCFcCores)

Buono, Gianmarco | Pappalardo, Lucia

2024

This data publication is related to the article of Buono et al. (2025) and contains the results of 4D X-ray microtomography investigations of well rocks from the Campi Flegrei caldera conducted at the micro-CT laboratory of the Istituto Nazionale di Geofisica e Vulcanologia-Osservatorio...

Results of analogue tectonic models of rifting and tectonic lineament reactivation along the Main Ethiopian Rift

Zwaan, Frank | Muluneh, Ameha A. | Liu, Jun | Kosari, Ehsan | Rosenau, Matthias | Corti, Giacomo | Sani, Federico

2025

This data set includes results from a total of 13 analogue tectonic models aimed at simulating the activation of tectonic lineaments associated with the Main Ethiopian Rift in eastern Africa. We use a model set-up based on previous work by Zwaan et al. (2021, 2022). This set-up involves a...

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...

Mechanical data of rotary shear experiments in bituminous dolostones

Chinello, Miriana | Aretusini, Stefano | Spagnuolo, Elena | Di Toro, Giulio

2025

Mirror-like Surfaces (MSs) are ultra-polished fault surfaces widespread in carbonate seismic terrains, but their formation process is still debated. We deformed gouge samples from exposed fault surfaces hosted in bituminous dolostone rocks in a rotary shear apparatus (SHIVA) at seismic slip...
