Magnetochronostratigraphic data from sediments in the Drake Passage – cores from expedition PS97, German RV Polarstern, 2016

Nowaczyk, Norbert R. | Liu, Jiabo | Arz, Helge W.

2024

Sediment cores were recovered during the ship expedition of German RV Polarstern in 2016 (PS97) using piston corers. For paleo- and rock magnetic analyses clear plastic boxes of 20×20×15 mm were pressed into the split halves of the generally 1 m long sections of the sediment cores. In...

Surface deformation and topography data from analogue modelling experiments addressing triaxial tectonics in regions of distributed extension

Liu, Jun | Rosenau, Matthias | Brune, Sascha | Kosari, Ehsan | Rudolf, Michael | Oncken, Onno

2024

This data set includes the results of high-resolution digital elevation models (DEM) and digital image correlation (DIC) analysis applied to analogue modelling experiments. Twenty generic analogue models are extended on top of a rubber sheet. Two benchmark experiments are also reported....

Database of mineral compositions within the lowermost oceanic crust accreted at fast-spreading ridges (Hess Deep, East Pacific Rise, IODP Leg 345)

Basch, Valentin | Sanfilippo, Alessio | Snow, Jonathan | Loocke, Matthew | Zanetti, Alberto

2023

This database contains mineral major and trace element compositions of gabbroic rocks composing the lower oceanic crust accreted at the East Pacific Rise and recovered at Hess Deep during IODP Leg 345 (Gillis et al., 2014a). Hess Deep is located at 2°15’N, 101°30’W in the Pacific Ocean, at...

A database of caldera collapse analogue models stretched under extensional conditions

Maestrelli, Daniele | Facincani, Pietro | Corti, Giacomo | Bonini, Marco | Vannucchi, Paola | Del Ventisette, Chiara | Montanari, Domenico | Keir, Derek | Sani, Federico

2023

This dataset presents the raw data from one experimental series (named CCEX, i.e., Caldera Collapse under regional Extension) of analogue models performed to investigate the process of caldera collapse followed by regional extension. Our experimental series tested the case of perfectly circular...

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...

Palumbo-Roe, Barbara | Shorter, Kirsty M | Fordyce, Fiona M | Walker-Verkuil, Kyle | Ó Dochartaigh, Ó Dochartaigh | Gooddy, Daren | Darling, W George

2021

The data release includes groundwater chemistry data from 15 samples collected during the borehole test pumping phase at the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This release from the British Geological Survey (BGS) covers groundwater samples collected between 14 January 2020...

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...
