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 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...

Data and scripts from Neighbouring segments control on earthquake recurrence patterns: Insights from scaled seismotectonic models

Latypova, Elvira | Corbi, Fabio | Mastella, Giacomo | Funiciello, Francesca | Moreno, Marcos | Bedford, Jonathan

2025

We provide particle image correlation data from the 16 laboratory experiments with Foamquake seismotectonic model simulating analog megathrust seismic cycles and supporting scripts. To monitor analog seismic cycles, we use a high-resolution camera taking images at 50 frames per second as an...

Analogue modeling results showing fault network evolution during multiphase triaxial strain

Jun Liu | Rosenau, Matthias | Kosari, Ehsan | Brune, Sascha | Zwaan, Frank | Oncken, Onno

2025

This data set includes the results of high-resolution digital image correlation (DIC) analysis and digital elevation models (DEM) applied to analogue modelling experiments (Table 1). Six generic analogue models are extended on top of a rubber sheet. In Series A, as extension velocity increases,...

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,...

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...

The noble gas isotopic composition of the upper mantle in non-arc oceanic settings: Inferences from fluid inclusion studies

Sandoval-Velasquez, Andres | Taracsák, Zoltán | Aiuppa, Alessandro | Rizzo, Andrea Luca | Romano, Pierangelo | Jackson, Matthew G

2025

OIB localities (e.g., Tristan, Samoa) have been considered ideal natural laboratories for studying mantle heterogeneity. Indeed, Sr, Nd, and Pb isotopes of lavas collected from OIB systems have provided insights into the existence of distinct mantle reservoirs, the origins of which are...
