Digital Volume Correlation (DVC) data from an analogue experiment exploring kinematic coupling of brittle and viscous deformation

Schmid, Timothy | Adam, Jürgen | Zwaan, Frank | Schreurs, Guido | Rosenau, Matthias | Hollis, Dave

2024

This dataset includes volumetric data sets from a Digital Volume Correlation (DVC) analysis for recreating images of a re-analyzed analogue models previously presented in (Zwaan et al., 2018). Using a brittle-viscous two-layer setup, this experiment focused on the evolution of a rift-pass...

Magnetochronostratigraphic data from marine sediments off Patagonia, SE Pacific – cores from expedition MR16-09 Leg 2, Japanese RV Mirai, 2017

Nowaczyk, Norbert R. | Liu, Jiabo | Hagemann, Julia | Arz, Helge W. | Iwasaki, Shinya | Murayama, Masafumi

2024

Sediment cores PC02, PC03, and PC04 were recovered during the ship expedition MR16-09 Leg 2 of Japanese RV Mirai in 2017 (Murata et al., 2017) using piston corers. For paleo- and rock magnetic analyses clear plastic boxes with a volume of 7 cm3 were pressed into the split halves of the...

Trace and major element concentrations of mineral phases found in ETZ-13 (alkaline basalt from the Main Ethiopian Rift) and glass/mineral compositions in the run products of experiments conducted at various P-T-XH2O in an internally heated pressure vessel using this basalt

Sauvalle, Romain | Scaillet, Bruno | Prouteau, Gaëlle | Scaillet, Stéphane | Cioni, Rafaello | Franceshini, Zara | Frascerra, Diletta | Sani, Federico | Corti, Giacomo | Melaku, Abate Assen | Andujar, Joan

2024

We have performed experiments on a basalt from the Main Ethiopian Rift (Ethiopia) to assess its pre-eruptive conditions in the magma chamber. The files contain all the analyses performed on the starting material (basalt) and the run products, both for the glass and mineral phases. Several...

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...
