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...

Contact model and numerical modelling results: “Compaction of the Groningen Gas Reservoir Sandstone: Discrete Element Modelling Using Microphysically Based Grain-Scale Interaction Laws”

Mohammad Hadi Mehranpour

2021

Reservoir compaction, surface subsidence and induced seismicity are often associated with prolonged hydrocarbon production. Recent experiments conducted on the Groningen gas field’s Slochteren sandstone reservoir rock, at in-situ conditions, have shown that compaction involves both poro-elastic...

Dense Seismic Array of Ambient Vibrations Applied for Site Characterization to a Liquefiable Site in the Po Plain at San Felice sul Panaro

El Hitti, Joya | Régnier, Julie | Cultrera, Giovanna | Di Giulio, Giuseppe | Minarelli, Luca | Gélis, Céline | Lenti, Luca | Langlaude, Philippe | Pernoud, Michel | Bustos, José Ignacio | Schibuola, Alessandra | Riccio, Gaetano

2026

The dataset consists of microtremor recordings collected from multiple arrays in mid-September 2024 at San Felice sul Panaro, located in the Quaternary deposits of the Po Plain (Emilia-Romagna, Italy). Data collection was performed using seismic nodes and six-component seismic stations: five...

Data from seismic slip-pulse experiments simulating induced earthquake rupture in the Groningen gas field

Luuk Bernd Hunfeld

2021

Rock materials show dramatic dynamic weakening in large-displacement (m), high-velocity (~1 m/s) friction experiments, providing a mechanism for the generation of large, natural earthquakes. However, whether such weakening occurs during induced M3-4 earthquakes (dm displacements) is unknown. We...

Trace element data obtained from main minerals in Salitre clinopyroxenite and dunite rocks (APIP, Brazil)

Guarino, Vincenza | Melluso, Leone | Bonazzi, Mattia | Zanetti, Alberto

2026

The Salitre intrusion, which is subdivided into Salitre I and Salitre II. It was dated to ~86-82 Ma by Sonoki and Garda (1988). It is part of the Alto Paranaíba Igneous Province (APIP, Fig. 1) in Brazil. The APIP is one of the largest ultrapotassic/carbonatitic/kimberlitic provinces in the...

Mineral trace element analysis of xenocrysts and xenoliths hosted in the Limeira I kimberlite (APIP, Brazil)

Guarino, Vincenza | Melluso, Leone | Bonazzi, Mattia | Zanetti, Alberto

2026

The Limeira I kimberlite (91±6 Ma; Guarino et al., 2013) is part of the Alto Paranaíba Igneous Province (APIP) and was emplaced in the southern part of the São Francisco Craton in Brazil. This Kimberlite contains macrocrysts and phenocrysts of olivine, resorbed phlogopite/...

Trace element analysis of the main minerals in the Salitre lamprophyre (APIP, Brazil)

Guarino, Vincenza | Melluso, Leone | Bonazzi, Mattia | Zanetti, Alberto

2026

The Upper Cretaceous Salitre intrusion, subdivided into Salitre I and Salitre II and dated to ~86-82 Ma by Sonoki and Garda (1988), is part of the Alto Paranaíba Igneous Province (APIP, Fig. 1) in Brazil, which is one of the largest ultrapotassic / carbonatitic / kimberlitic provinces in the...

Trace element concentration of minerals in the Morro São João malignites (Serra do Mar, Brazil)

Guarino, Vincenza | Melluso, Leone | Bonazzi, Mattia | Zanetti, Alberto

2026

The Morro São João intrusion is located in the easternmost part of the Serra do Mar province, along the Cabo Frio lineament (Fig. 1) and has an area of approximately 10 km². It is a Late Cretaceous intrusion formed by clinopyroxenites, melagabbros, shonkinites, malignites, nepheline syenites,...

CAMSIZER Particle Size Data from Explosive Paroxysms of Mt. Etna (2011–2025)

Tonato, Andrea | Andronico, Daniele | Corsaro, Rosa Anna | Caruso, Simona | Pistone, Mattia | Cristaldi, Antonio

2026

Mt. Etna in Catania, Italy, is an active volcano that has served as a natural laboratory for many volcanologists worldwide. Its paroxysms are unique eruptive events caused by a complex magmatic system that, despite being one of the most studied volcanoes, there is still an open field to...

Frictional slip weakening and shear-enhanced crystallinity in simulated coal fault gouges at subseismic slip rates

Jinfeng Liu | Luuk Bernd Hunfeld

2020

We report seven velocity stepping (VS) and one slide-hold-slide (SHS) friction experiments performed on simulated fault gouges prepared from bituminous coal, collected from the upper Silesian Basin of Poland. These experiments were performed at 25-45 MPa effective normal stress and 100 ℃,...
