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...

New and compiled palaeomagnetic data from western Ross Sea (Antarctica) spanning the last ca. 10 ka

Sagnotti, Leonardo | Caricchi, Chiara | Macri, Patrizia | Colizza, Ester | Del Carlo, Paola | Di Roberto, Alessio | Winkler, Aldo

2025

This dataset includes both original and previously published paleomagnetic data. The new data refer to a marine sediment sequence (ANTA02-AV43 core) collected in the in Wood Bay, located along the coast of Victoria Land, within the western Ross Sea (Antarctica) and spanning the last ca. 10...

∂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...

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...

Carbon isotopes in OIB Mantle source

Lo Forte, Francesco Maria | Rizzo, Andrea Luca | Aiuppa, Alessandro | Sandoval Velasquez, Andres Libardo | Romano, Pierangelo | Maffeis, Andrea | Frezzotti, Maria Luce | Casetta, Federico | Ntaflos, Theodoros

2026

The Atlantic Ocean hosts a number of intraplate volcanic islands that provide crucial information on mantle plume dynamics, volatile budgets, and the role of recycled components in the deep Earth. Among these islands, Sal (Cape Verde archipelago) and Madeira represent contrasting examples of...

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...

Noble Gas Isotopic Composition from Geothermal Springs of the North-Western Himalaya

Choudhary, Shubham | Thakur, Mahesh

2025

This dataset contains noble gas (He, Ne, Ar) isotopic and elemental compositions of geothermal spring fluids collected across the North-Western Himalaya as part of the “Himalayan Geothermal Project: Investigating Geothermal Systems in the North Western Himalaya – Origin and Tectonic Influence”....

SLIDEX Extreme climate-tectonics controls on landslides

Capitanio, Fabio | Reitano, Riccardo

2025

We implemented, by means of analogue laboratory modelling, the key processes of the feedback among erosion and landslides, isostatic response and lithospheric flexure, to address how these lead to landsliding. The processes involved have different response times and characteristic length-scales...

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...
