A database of analogue models testing the interaction between magmatic intrusion-related doming and caldera collapse

Maestrelli, Daniele | Sani, Federico | Bonini, Marco | Montanari, Domenico | Del Ventisette, Chiara | Corti, Giacomo | Renzetti Pagnotta, Diego

2024

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...

Experimental insights on experimental volcanic lightning under varying atmospheric conditions

Springsklee, Christina | Scheu, Bettina | Seifert, Christoph | Manga, Michael | Cimarelli, Corrado | Gaudin, Damian | Trapp, Oliver | Dingwell, Donald B.

2023

This data publication provides data from 39 experiments performed in 2021 to 2022 in the Gas-mixing lab at the Ludwig Maximilian University of Munich (Germany). The experiments were conducted to investigate the charging and discharging potential of decompressed soda-lime glass beads in...

Stable Nitrogen isotope composition of common wheat in intercropping with Persian clover (Tuscany, Italy)

Baneschi, Ilaria | Furlanetto, Nicola | Boschi, Chiara | Pellegrini, Ferdinando | Antichi, Daniele | Barberi, Paolo

2024

Intercropping is the simultaneous growth of two or more crops in the same space for a significant part of their life cycle (Willey, 1979). In this context, samples from one farm experiments in the growing season 2015/2016 and 2016/2017, embedded in the cropping systems of one arable farm in the...

Ring-shear test data of garnet sand used for analogue modelling in the experimental tectonics laboratory at GFZ German Research Centre for Geosciences, Potsdam

Rosenau, Matthias | Pohlenz, Andre

2023

This dataset provides friction data from ring-shear tests on garnet sand used in analogue modelling of tectonic processes as a rock analogue for “strong” or “high density” layers in the earth’s upper crust (e.g. Klinkmüller et al., 2016). According to our analysis the material shows a...

RST Evaluation - Scripts for analysing shear experiments from the Schulze RST.pc01 ring shear tester

Rudolf, Michael | Warsitzka, Michael

2021

The software RST Evaluation is a series of scripts to semi-automatically evaluate shear experiments done at the Helmholtz Laboratory for Tectonic Modelling. In principle, it may be used for other measurements done in a similar setup, but it was build with our standardized workflow in mind....

OGS Core Logging Lab - logging sediment cores in Lago Argentino (Brazo Sur), Argentina

Caburlotto, Andrea | Caffau, Mauro | Lodolo, Emanuele

2025

The spectacular water outburst occurring semi-periodically when the ice-dam formed by the external front of the Perito Moreno glacier collapses, is one of the most attracting events in the UNESCO ‘Parque Nacional Los Glaciares’ of southern Patagonia. These occurrences have been documented since...

In situ EMPA and SIMS investigation of mineral geochemistry of mantle xenoliths from Cerro Nemby (25°24' S, 57°32' W), Paraguay

Bonazzi, Mattia | Zanetti, Alberto | Margutti, Roberto | Mazzucchelli, Maurizio | Vannucci, Riccardo

2023

Mantle xenoliths are hosted in lavas localized in the Nemby area (25°24' S, 57°32' W; Asunciòn-Sapucai-Villarrica graben, ASV, central Paraguay: Fig.1), where a small melanephelinitite plug (Cerro Nemby), with elliptical topography (800 x 500 m, about 100 m above the plain), contains very...

In situ EMPA and LA-ICP-MS chemical analysis of mantle xenoliths from Sierra Baguales (50°S), Patagonia

Bonazzi, Mattia | Zanetti, Alberto | Margutti, Roberto | Vannucci , Riccardo

2023

The Patagonia is a vast region located in the southernmost tip of the South America continent. It shows a basaltic plateau formed by volcanic activity started in the Upper Cretaceous-Lower Cenozoic (e.g., Baker et al. 1981; Ramos et al. 1982) and continued during Plio-Quaternary period. Long...

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,...
