This dataset contains a series of analog models for comparing and testing positive tectonic inversion mechanisms and wedge structure formation. Furthermore, it includes a 2-D seismic reflection profile that can be compared with the models presented here. Finally, several photos of some...

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,...

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...

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,...

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...

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...

Multi-collector 40Ar/39Ar data of glass and plagioclase from a tuff sample in the marine claystone of the Argille di Spadafora (NE Sicily, Italy)

Di Vincenzo, Gianfranco | Dorsey, Rebecca J. | Meschis, Marco | Longhitano, Sergio G. | Cavazza, William | Chiarella, Domenico

2025

The dataset contain full 40Ar/39Ar geochronological data completed by multi collector noble gas mass spectrometry on plagioclase and glass separates from a tuff sample interbedded in Pleistocene marine claystone (Argille di Spadafora) of northeastern Sicily (Italy). Tuff unit VU7 was identified...

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...

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

Zwaan, Frank | Muluneh, Ameha Atnafu | 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...
