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...

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...

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,...

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...

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...

A Database of Centrifuge Analogue Models Testing the Influence of Pre-Existing Weak Zones During Continental Compression

Wan, Xiaofan | Maestrelli, Daniele | Corti, Giacomo | Sani, Federico | Bonini, Marco | Ge, Xiang | Lei, Qingqing | Zou, Yaoyao | Shen, Chuanbo

2025

This dataset presents the raw data of an experimental series of centrifuge models performed to test the influence of pre-existing weak zones in the lower crust (herein after referred to as Weak Lower Crust –WLC) during continental compression. We varied the width of the WLC, the dip of the...

∂13C data of picrite rock samples from St Helena Island (South Atlantic Ocean)

Sandoval Velasquez, Andres Libardo | Aiuppa, Alessandro | Rizzo, Andrea Luca | Romano, Pierangelo | Taracsák, Zoltán

2025

This dataset includes ∂¹³C data of fluid inclusions hosted in lavas from St Helena. St Helena, a small volcanic island in the South Atlantic Ocean, represents one of the classic examples of ocean island basalt (OIB) volcanism associated with intraplate mantle plumes. Although the island is...

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...
